We’ll get the other characters of the banner poster in the coming day. But, hey can’t wait that long, so from tweaking the picture and thanks to some tidbits leaked here an there, we may guess a few more characters:

So we may recognize on this poster of Toy Story 3:
– Peas in a pod
– Mr Pricklepants the porcupine
– Lotso the pink Teddy Bear

And we may also guess from left to right:
– a little girl with purple hair?
– two shadowy creatures
– a nerdy green worm
– a baby doll?
– a green creature with antennas who holds a staff (a Yoda-like insectoid?)
– a squid
– a small horse, or is it a dog?
– a crab
– a monster who kind of looks like the Thing from the Fantastic Four

Anyway, tomorrow a new trailer of Toy Story 3 will be released, maybe the new characters will show up in this trailer.
