Lowest common denominator. Especially for consoles. Remember, consoles were supposed to be the "Buy it, and never have to buy an add-on to enjoy top of the line games" unlike a PC. By seperating the crowd, developers will spend LESS time on anything that will use the HD, because like a lot of people are saying, it's splintering the community.
If the X-Box HD is being underutilized now, it's gonna be completely dismissed by a majority of companies, or not used to it's full potential.
