Just wait and see what they do with this concept, although it does feel a tad restrictive taking into account the kind of games this thing will be useable in. Expect plenty of first person shooters, Mario Parties and probably a bunch of fighting games that somehow use this system to deal blows. Basically what we're looking at is a companion piece to the Nintendo DS, which I'll admit hasn't exactly BLOWN me away thus far aside Jump Superstars, but the real meat of the games are due soon so we'll see.
All I feel that's left to say is... roll on Revolution.
