Are the new Pokemon games 'new'3ds exclusive?
No, but there are compatibility issues in the games themselves to be aware of. Omega Ruby/Alpha Sapphire have a few items, moves, and Mega Evolutions that cannot interact with X/Y. Also, when you go online for a random Rating Battle, the "league" that accepts the OR/AS specific features will NOT accept any Pokemon that were not originally caught on a 3DS game.
I don't expect a "New 3DS" exclusive Pokemon to ever happen. Pokemon embraced DSi enhancements without being exclusive to it and was EXTREMELY late in moving to the original 3DS. Historically the series isn't that big on pushing new hardware, especially not in terms of processing power. And it's not as if the C-Stick/extra buttons are of any real importance to a Pokemon game.
I WOULD appreciate if they could use the N3DS's extra power to keep the 3D effect on more often, though. It's bizarre how frequently the games jump between 3D and 2D modes.
