The International timeline.
It's just wrong.
I'm actually revamping my own site at the moment, since I'm still in lockdown. But I can definitely point out how and where it's wrong. The problem is I have done so at least 3 times in the past when people have mentioned updating and nothing gets done about it.
I'm also not sure if it can be fixed without abandoning the idea of separating international ponies and "US" ponies, because not all the international ponies were sold in the same places and often they also weren't sold in the same years as the 'equivalent' 'US' sets. (Not to mention most of those US sets were also sold overseas, so it makes trying to ID a collection if you grew up in the UK or Europe much harder. You have to dart around between "US" and "International" and there's no way someone who just wants to ID the ponies they bought in the UK knows which ones the site thinks are 'US' and which ones they don't.
But that;s a bigger systemic issue that probably Absol would have to fix.
In the meantime...

(Side-note - I'd love to see the end of the year system, but esp. this idea that years after the US ended can be tagged as 11, 12 and 13. That makes no sense since it relies on the assumption all ponies began at the same time as they did in the US, and that's not the case.)
CP AJ and Bow Tie are included under the 1984 set. They belong in 1985. They're Groom & Style Ponies.
Regentropfen and Nachtlicht are included under "Year 3" to fit with the y3 rainbow ponies.
None of the others from their set are included here.
They were actually sold in 1987. They have nothing to do with the Y3 set.
Baby Applejack, Baby Bow Tie and Baby Lemon Drop are all lumped together under Year 3. Baby Applejack is a Play & Care Set Baby and belongs with Baby Cotton Candy and Baby Blossom. Baby Bow Tie is the stroller baby for 1985 so is in the right year but shouldn't be with Baby AJ. Baby Lemon Drop belongs in 1986, so Year 4.
I am not sure if this one is a problem as it makes sense really for them to be together, but the Pretty & Pearly UK versions of the baby sea ponies belong to 1987/y5 rather than Y4.
Tutti Frutti and Wedding Bells Confetti seem entirely missing. So do the Movie Star ponies. But I'll come to those in a moment, they're on the other link...
Mountain Boys belong in year 5 (1987). They're currently under year 6.
Baby Nightsong, Stella etc are not Sparkle Babies, they're Starlight Babies. It's a different set.
Year 11 is missing and year 12 is a questionmark, which kind of sums up my opinion on the year system and international ponies ;)
...A lot of ponies are missing from 1990-2 that were sold overseas. I haven't tried to work out how many international ponies overall (not including Nirvana) are entirely absent from this list. Cascade, for example...
I think this is evidence of how far Absol got in integrating the list, but it's not complete and there are the above errors.

Please note Absol's date-stamp. That's how long it's been.

Year 3
German Rainbow Ponies do not belong in this year. They are from 1987.
Year 4
Tutti Frutti does not belong here. She is also 1987. This is a good example of trying to forcibly connect an international release to the US timeline, because the US set was in y4. It really didn't work like that.
Cascade is here, but I think she belongs in Year 3. She's 1985, and almost certainly came out in the UK before Sprinkles, who was also 1985.
UK Cherries Jubilee and magenta posey are missing from the set with Gypsy and Honeycomb, Hopscotch and Snowflake. This also isn't demarcated as a set in its own right, but it is one.
Kiss Curl wasn't sold until 1987-8 at the earliest. Probably 1988.
Baby CJ, Hopscotch and Honeycomb are mentioned here, but no Baby Buttons. These also should be in 1987. They are a separate set in their own right, along with a version of Baby Lemon Drop.
"Alternates to American Ponies"
Frankly I find that offensive.
Gusty and North Star are Movie Star Ponies. They belong in 1987. The rest of their set are not here.
Where is Wedding Bells Confetti?
Year 5
I'm not sure what is going on here with 'alternate Princess ponies'.
If they're the German other releases, they should have German names.
If the UK weird puttogether princesses, they belong at the very end of the line.
The ponies under these names are not alternate ponies. They're just the UK names for the regular princesses.
Mountain Boys are not here.
Year 6
Mountain Boys should not be here.
Year 7
White club baby belongs to 1989.
Year 8 is confusing because it's merging together 1989 and 1990. I don't even really want to begin with this, but I do like that Starlight Babies is included as a setname here.
Why are Sweet Clover and Rosette lumped in with Baby Bridesmaid, who is a club baby?
The year system becomes a problem at this point because the Romance ponies etc were part of 1992's release according to Hasbro's list. The Seven Characters were in 1993. But I don't think of 1992 here as the same as year 10 in the US.
I think Baby Ribbons & Hearts is earlier than she's currently listed. But she's a bit complicated.
The ponies listed for 1992 and 1993 are correct, but the years should really be 1993 and 1994 based on the list I have from Hasbro UK.
...UK releases at the very least were done by calendar year, not by Dream Valley's year system, which is one reason it's so hard to shove them into US years.
I think what Absol was trying to do was migrate the exclusives into the main timeline, which is a good thing. But they need to be migrated in the right places, with the right set names, and with everyone present and correct. Otherwise it's a bit of a wasted effort.
