My question is are those TVs they got the Xbox 360 hooked up to supporting 720p mode or are they just standard 480i/p? I work for Walmart too and I haven't seen one at the store I work at yet here in California. I hopefully will be getting mine on launch day, as I pre-ordered one and my friend is the head manager of the store and pretty much said that I would get one no matter what.
From the videos that I have downloaded of the games from Gametrailers.com
the HD videos look really, really good.
I does tend to make you wonder if M$ when they redo Live for the 360 launch will have those demo games available for people to play for launch day so that people can play the game and then go back to the store to buy them.
