NO NO NO.
HUGE STEPS have been taken between each generation. The gaps between the first three were the SMALLEST. Gen 4 introduced the second Physical/Special Split, completely altering the game play. Gen 5 introduced THE FIRST PLOT TO EVER EXIST IN A POKEMON GAME and then it introduced the second (the second was much worse though D

. You can't compare Black and White to their sequels because THEY ARE SEQUELS. They are NOT a different Generation. You can't expect them to change much. Think about Platinum. How much did that change from Diamond? None. It didn't change a thing. Don't even try to say that it did. People liked Platinum anyway. Now look at BW2. By all rights, NOTHING should have changed at all between BW and BW2. No one was expecting it too. But then EVERYTHING CHANGED. It was almost as good a sequel as we could of hoped for (Damn you obvious plot twist!).
Black and White added so much more to the table. Think how much the meta changed because they FINALLY added more abilities to the game. Think How great it was that Black and White were actually TWO different games instead of the ol' "Let's change the legendary and sell it for the same price!" THINK about how lists are always better with a third thing.
What did they do in between Gens II and III. They added double battles, something that was in the anime from the first season. What did they do in between Gen IV and V? They added triple battles rotation battles, a completely novel concept that NO ONE saw coming.
They have NOT pulled a CoD, at least not yet.
----------------------------------------------------------------
They have NOT pulled a CoD, at least not yet. Why?
A. The game has changed in every installment.
B. BW and BW2 weren't the next installment.
What do I mean by that? The 3DS had (1) just come out and it was (2) selling poorly, however the team wanted to make (3) a full 3D game because (4) who wouldn't. Meanwhile, they had (5) ideas that didn't require full 3D and (6) people who wanted new Pokemon and (7) still didn't have 3DS's. Therefore, Gen V was a STALLING generation, not a full generation, that managed to beat the odds and turn out amazing despite the limited time spent on it, similar to (8) Majora's Mask. Gen V was a steeping stone to full 3D, where they set up more concepts and better graphics for Gen VI to build off of.
...At least in my eyes.

Finally some minor points.
I'll miss the classic pixelled sprites of old, however they were kinda terrible with Gen V's dynamic camera.
If Fennekin is Fire/Fighting I will never play another Pokemon game.
