I dunno but if you look at the silhouette itself, the feet of the one on the left look unlike any other pokemon feet I've seen yet.
They definitely don't look like bird feet or even dragon feet. Also, if you notice what many believe to be the neck, but in the picture is a head, it seems a bit too lumpy to be a neck and too small for a head, even a bird's head like in that picture. It's a bit too disproportional to me. Also, the what would be the arms look way too small when you consider it's legs are of equal, if not shorter, length than the arms. And finally, the weird beak thing that comes out of it's neck/head. I suppose this is the reason many think it could even be a bird but, generally, in the past, all of the starters had full appendages in arms and legs, whereas in that picture, it has no arms.
The tail structure is also interesting, again, no other pokemon has a tail like that. Which makes me think, maybe it's not even a tail fin. Maybe it's connected to what would be the beak and the tail just happens to overlap it in the silhouette.
I dunno, food for thought.
Oh wait, one more thing, the "bunny's" ears. If you look at the ear on the left, it seems to be moved upward just slightly. It also appears to be longer than other ear which makes it seem as though, it's either bent at a very weird angle or actually attached to each other which could very well mean it's a leaf(Chikorita clone!)
Then finally, the one on the right. The enormous head seems to be a hat of some sort to me. Starters generally tend to be fully mobile in that they can move their entire body. If it's head was actually that big, it seems as though it's neck would be far too bulky to even move it's head which would make it a sort of waddle-for-movement pokemon which doesn't seem right when you consider the other starters.
Ehh... Hopefully tomorrow they get revealed. Saturday is too long of a wait.
