I like the controls they showed earlier for the xbox, especially if the voice recognition works nicely. Reminded of the computer from star trek lol.
I think these games will sell well with the casual gamers (a large portion of wii owners). It will be interesting to see how things pan out with this and PlayStation Move, i think Nintendo will have allot of competition.
Although as said by others, real games plx!. Casual ones are all well and good but share the love microsoft.
Apart from the first little bit the entire show so far seems to be a big up yours to Nintendo "look at us, we can do better".
