i dont believe you will need windows media center edition for the ps3 but i dont think sony will put enough money into the media server part of the ps3's development.
i do believe however that by the time of ps3's launch, you will be able to play all codecs on a modded x360 from a custom (500gb?) hard drive, or have it streamed from a non mce pc.
if you dont want a mod xbox 360 then it looks like sony is the right choice because as of yet the x360 only supports mpeg2 (dvds), mp3, wmv, wma and a couple of others. no hd-dvd divx xvid yet.
sony will probably support a large range of 3rd party codecs and Blueray.
also we will have to wait and see who wins the dvd race. blueray or hd-dvd.
