earlier this year, there was some debate about whether or not Pioneer's new 400GB Blu-ray disc would work on currently players. DIGITIMES is reporting that the new 16-layer discs will work on current Blu-ray players, which includes the PS3. These super high density discs won't be available until 2010, just in time for Hideo Kojima's next game.
Update: Looks like we have some contradictory information: Speaking to Edge, Pioneer said the opposite was true. "Current BD players and drives would not be able to read these discs," the company said, adding that the technology is "at this time not being proposed as a candidate for addition to the existing Blu-ray Disc format."
