All they did there was recolour the mane cast... I am disappoint.
Um... That's how the toys work. I don't know why My Little Pony fans keep acting surprised by it. They may have been slower than usual to come up with new poses for G4, though...
I actually like seeing how the G3 ponies are updated for G4, imagining old favorites coming back in a new world. Am I the only one who thinks it's funny that Skywishes is now a pegasus pony, considering that the story of the original Skywishes was that she was the first pony from Ponyville to meet a pegasus? Maybe that was her final special wish, to be able to fly on her own.
And yeah, it also occurred to me that the TV show could use some of those new versions of the classics as "foils", or at least a way for the show to poke fun of itself and previous MLP cartoons. Remember that whole "rival town" discussion? There could be another gang of six ponies there who cover the same diverse range of interests, but in truth are a lot less accomplished than they think of themselves, making announcements like "But we're not just any ordinary group of friends! We've been charged by Princess Luna herself to investigate the TRUE POWER of COMMUNITY SPIRIT!"
As for possible members of that gang, Minty could have the same sunny disposition of Pinkie Pie, but now suffers from confidence issues as everyone is well aware of how often she screws everything up. And hey, remember Rainbow Flash? That could be your parody of the original Rainbow Dash
and Rarity, a unicorn who so loves producing rainbows everywhere that even Rainbow Dash is freaked out. Sunny Daze could make a good counterpart for the new Rainbow Dash, only her new appearance would be the grown-up version of that one baby doll they made. I had trouble deciding on the best foil for Twilight Sparkle, but then I noticed that Dewdrop Dazzle was already popular for that in the fandom. And then... I dunno who else, maybe add the orange bumblebee pony 'cuz she's cute.
