So, X-Box is going with Dual Layer DVD for easy in use / low cost...
Nintendy is going with "12 cm optical disks" to fight piracy (again)...
And Sony... well, Sony loves their Blu-Ray, but without a clear win in the Toshiba / Sony fight, that's a tough call to make. Considering that the PS3 was announced to be Blu-Ray last year, I don't really expect that report to hold water come E3.
Nintendo makes a lot of money making other companies pay for their techology (as opposed to DVD technology), but they're not making friends in third-party developers doing it. I hope they've got something amazing to offer developers, or the Revolution is never going to get to enough homes.
