I for one, am for generation V. I agree with you though, Gamefreak734, they should let us wait untill everyone wants new Pokemon, I think they should slow down a little. I mean I first discovered that GSC exsisted when I was little, then Ruby came out, then emerald, the fire red, then diamond! IT WAS MADNESS!! A way to put it is, a huge whole was being burnt into my pocket.
On another note, I don't beleive that they can really run out of ideas. And who said that it had to be animals? Rotom is what? A bolt of electricity, its a pretty decent Pokemon right? They could start just coming up with things, and they can still use ghosts, plants, shapeshifters, and even humanoid creatures.
