What if Green had to be Bulbasaur!
I think theres something on Pokemon.com about both the version, and the release date. (How ever, at this time it won't let me on!) Sorry.
I'm 98% sure its gonna be green. Why go through the trouble of changing it again. Besides, us Bulbasaur/Plant lovers know that Blastoise has already had the spot light. Although, ya know what'd be intresting. If you got the color, and had to get that pokemon (this would only be intresting if all FOUR came out, yellow, red, blue, and green)
That'd be cool, cause then people'd have a reason to trade. Blue could have more water pokemon then say, green. (Red Fire, Yellow just general, exc.)
Well there's my opinion n.n
(Actually, thats what i thought when I first got red (first game i got) back when it came out.)
That with red you had to pick charmander, blue squirtle, exc. Yellow already has this anyway...::goes off and rambles to himself::
