for all those thinking deeply on the subject, Xbox 2's real name is going to be XBOX Next. and its gonna come in three styles, "Xbox" next which is the standard model (it will not have a hard drive= cheaper),
Xbox next HD (will feature a hard drive), and the Xbox next PC. the PC version will be a cheap computer alternative, it may or may not have windows but it will have a web browser and a cd burner, but thats all I know for now.
PS: get the Xbox Next, because then you can play Morrowind IV oblivion! with busting out big money for a 6800 gt, or X800pro so you can play the PC Version.
