Is Lost coming to my Xbox?

Ahh, now we’re seeing what Microsoft is thinking of doing with Xbox as a media-distribution platform (Microsoft is announcing TV programs and other video shows distributed onto your Xbox). My question is: can I watch Lost? I don’t have a TV hookup, so I have to either wait for IP networks to get it (and I ain’t gonna watch 640×480 on iTunes, that’s too low a resolution) or I have to wait for NetFlix to get it on DVD. We just finished watching the second season of Lost. I want to get the third season of Lost for a reasonable price. In HD of course.
