G3.5 are the new G2, in that they're the new 'lost' (as in the point was completely lost on everyone!) generation! I don't think they'll have a massive comeback like the G2's did, but some collectors love them.. But even if they did there's only 10 unique characters, so it wouldn't last long, lol!
Congrats on your new pony though, any pony is a good pony, I say!!
