Unless both sides were to sit down and hammer out a single HD blue-laser format, there's not likely going to be a real winner declared for several years yet. Even if Toshiba's prediction is true and those 4 studios decide to support of HDDVD, that's no guarantee that the consumer will decide in favor of HDDVD. For example, if more people are initially interested in BRD boxes because they offer recording capabilities that the HDDVD camp hasn't talked much about yet, then the studios offering pre-recorded content on BRD are likely to sell more units, whether there's fewer of them doing so or not.
Likewise, it was premature for Gizmodo to pull this "BRD has already won" line on Monday and its equally premature now. It's not altogether clear yet how competitively BRD can be priced relative to HDDVD to start. It's not really going to matter how much more technically impressive BRD is if manufacturers and studios can't price that added value sensibly and/or make consumers see it as such.
