I just checked over at 1up.com and apparently they have a preview done from the full version of the game. They said that controls are now fully map-able, including touch screen use, but that they played through over 40% of the game in something like 2 hours. So we've moved from possible control problems to a short single player game.
The shining beacon though is that apparently it supports single cart play, and is 2-8 players. It also supports multi-cart play and I dont know what the difference is between the two as far as levels, characters, options, etc.. go.
I haven't seen any actual reviews out, but give it a few days and at least we should get some reader reviews if nothing more "professional".
Btw, as a sidenote Kirby:CC has gotten really great reviews, generally 9/10's
