5th Gen So a new start?

[might will fate]

So asi think no more cross gen evolutions for gen 1-4.As i think now the regions will be based at america for four regions then at europe so its like to start a whole new gen for this the pokemon numbers 156 pass the first gen.

I'm pretty sure basing the region off of America was a one-time thing. Evolutions and pre-evolutions will likely return next generation, as the only reason none were introduced this time around was to enforce the whole "recreating the Red/Blue experience" thing Black and White have going on.

This doesn't really relate to B/W - considering this question is about future games. Go post it in General Pokemon Gaming somewhere.
