WMA and WMV support only? (Score 1)

As it is a Microsoft product I suppose the only type of media that will be supported is WMA and WMV files if they add video. I'm not really found on converting all the files I have to other formats to get them to work on another device. If Microsoft would stop trying to dominate the world and support other formats I think it would have much more chance of success. Blah... This thing is going to suck, I can already tell.
