Aside from the fact there might be licensing issues that could hold the hardware hostage, you need to think of the software side. That could turn to be a BIG issue; one could present a good comparison to the Beta thing; a big part of it's downfall was lack of software.
One possible smart move by one of the camps, as suggested by ah802 in another thread, is a dual sided disc w/DVD9 on one side and HD on the other.
