Gamertell: "Sony went all in betting that Blu-ray technology would win the next-gen video disc wars, adding Blu-ray capability to its PlayStation 3 consoles.
Microsoft, on the other hand, hedged its bets with the HD-DVD format. While the console didn't come packaged with HD-DVD capability, gamers could purchase an add-on drive to upgrade. So at the last CES (2008) when Warner Bros. ended the war by announcing it would no longer support HD-DVD, it certainly looked like a win for Sony."
