Just a second, I messed up. Rayman does have 16:9 support, but Trauma Center doesn't. On the other hand, Rayman has no 480p support, while Trauma Center does. It's on IGN.
As for the digital box, people who are still receiving broadcast over an antenna will either have to get a digital TV, or get a converter that will changed the signal into a format the regular TV can read. I guess there is talk of the US government helping people buy one or two with coupons.
