Do you know if xbox live offers full game downloads or is it just the arcade style games? Sony is doing a good job of nudging digital distribution by offering some of the Blu-ray games on PSN (Warhawk, GT5P, Fatal Inertia, Siren, and Socom). I like the fact that Sony seems to have some standards on the type and quality of game that they will publish on the PSN.
Edit: Wrong Thread.
Thanks for the input, Jeff.
