1. Nearly all current Blu-ray players are obsolete: The Blu-ray standard is still evolving. Most models currently available use the original Profile 1.0 standard, while some newer models use Profile 1.1 (which adds the ability to show picture-in-picture commentaries). Later this year, the first Profile 2.0 players--which add the ability to deliver online special features (BD Live)--will become available. Ironically, both of these are designed to bring the Blu-ray standard in line with HD DVD players, which have long been able to deliver these features.
A couple of the most recent Blu-ray players (the combo players from Samsung and LG) can be updated from Profile 1.0 to 1.1 with a downloadable firmware update. But the PlayStation 3 is, supposedly, the only existing Blu-ray player that will be fully upgradeable to Profile 2.0. So if you don't want your Blu-ray player to be obsolete, the PS3 is your only choice until 2.0 models--such as the Panasonic DMP-BD50--hit later this year. . . .
