It seems like it. They're adding a few new Elements to the game:
3 vs 3
All new type combinations (Dragon - Fire, Psychic - Fire, Dragon - Electric)
The World is more three-dimensional, with cities that aren't simple grids any longer.
Yet they're keeping most of the same elements that made every game good. Training, battles, Wi-Fi is still there, along with some sort of minigame (Pokemon Contests/Pokethalon/ect)
And while some say the pokemon look too cartoonish, you gotta realize... That's what they've always been... Cartoons... >~>
Anywhoo!! I think it looks wonderful, and I've already pre-ordered Black. ^-^ Good luck whenever you get it!
