The PS3 could do that. Except it didn't work well for a few games. I remember horrible frame drop experience on Assassin's Creed, which was due to a game or demo that was downloading in the background. Also, think of the power user case. I'd much prefer a 3W processor waking up during the night doing silent updates, instead of the whole 100W monster (or maybe a fifth of that if they do intelligent power-gating).
