yep, all the G3 sites say the first 50 runs were identical to the actual releases, but I thought I'd remembered a few ponies(like yours) were not the same...until yours showed up, I had been half convinced I'd just dreamed it up or something!
The first colors for April were differant as well, but I've never actually seen one, just the picture, and that was so long ago I can't remember what she looked like! I just remember being excited cause she wasn't pink, and then disappointed when I found them in stores...and they had changed the body to a bright pink(just to spite me.
)
