I personally am not too excited about the whole "3 dimensional" aspect for the new game. One of the things I've always liked about older sprite games is how simple they are, they complimented the age demographic they were intended for, because they replicated the drawings of the show, yet still allowed for the imagination to fill in some gaps.
Also, about he whole "it's hard coming up with new idea's" thing is such a cop out, It would be so easy to get some newer people on the gamef reak team to come up with new pokemon ideas. I mean there's 100's of sick looking "Fakamon" out there, and I think it would be pretty cool if the took some of those (sort of like a contest to "create your own cool pokemon" that a decent amount of other companies have done).
...but that's just me.
