Hi - Def is only 'kind of' now. Yes, the HDTV's are becoming more prevalent, but they are not yet in every home. That isn't a big deal, but the reality is that even on HDTV's, we are seeing too many people still use standard definition transmissions on them. Half the bars I go to have beautiful HDTVs but are using SDTV satellite signals or SDTV cable signals. HDTV is an 'extra' on satellite tv and cable TV. Very disappointing, and is holding HD back from being completely pervasive.
Quite frankly, I agree with Nintendo's premise. HD is not a necessity for gaming. Their games are truly innovative wit their input. I hate the console controller. I do not have a Wii myself, nor do I ever intend to get one, but I certainly enjoy playing it, over any other console, when with friends and family. Nobody cares how it looks. Everyone loves how it plays.
