Both Microsoft and Intel will be backing Toshiba’s effort to make HD-DVD mainstream. Microsoft has already given their support to HD-DVD through previous partnerships, and now they’re going to be more or less reiterating their support. Intel, too, are putting their weight behind the HD-DVD format. On the other side, companies like Apple, Sun, and HP are supporting Blu-ray.

I don’t think this really changes much. I still think Blu-ray will win the day when all the chips are counted.
