I see your point, but if this 'formula' changed then it won't be Pokémon would it?
At it's core Pokémon is a turn based RPG. That's what it is and what it set out to be.
Masuda:
Generations 1-4 had seen a few major innovations, but with Gen 5 and especially the recently released Black 2 & White 2, I think the Series is heading in the right direction.
Especially with the Story and direct sequels, thanks to this I think Unova has a lot more going for it when compared to some of the other regions simply because we get to see how the region changed after 2 years, it gives you a sense of 'importance' or 'liveliness' everything isn't the same, it has changed this isn't a one-time-visit it's more dynamic.
Also thanks to the improved infrastructure of the 3DS, we should see some other changes that are brought to the table and new, innovative ideas are born thanks to its many features.
I think you should give Black/White & Black/White 2 another chance.
