Help me with a list of G4 releases?

[Flitter]

Out of curiosity I'm working on a list to figure out exactly how many new brushable characters hasbro has been releasing each year.
I think the very first G4s started being released Oct. 2010 so I'm using fiscal years, starting 1 Oct.
There are several that I'm unsure exactly when they were first found in a store or first in stock online. I'm counting when they were first available to buy, not when they were first shown/seen.
I'm considering the first release of the character worldwide of new regular size "playful pony"-like brushable characters only.

Here's my rough list so far.
Can anyone help me make corrections if it needs any?

Looks like a pretty complete list to me Man, look at all that variety in the first two years! Now I can really feel the 2012 dropoff that made me consider stop collecting G4... Eight out of nine ponies didn't come to Australia. Even in 2013, three ponies are N.American store exclusive, one has come here, three newbies have yet to turn up. Is there supposed to be seven or eight ponies that year? Seven names are listed but the top says 8 ponies.

Thanks, I changed that one to 7. I know such a drop-off and with so many being exclusives too!
