Most of us don't want to spend money on two players, especially if one becomes obsolete in a couple of years. HDDVD and Blue Ray are both still pretty new, so I don't mind waiting for cost reduction, player improvements, and either a universal player or a format winner.

I'll probably do mine as part of a HTPC as well. I have been waiting for the cable card that does HD for the HTPC. I know they are out, but they are either expensive or a bit tough to find still.
