Game xStream and DISCover PC Gaming Partner to Offer First Windows Media Center On-Demand Gaming 
One of the things coming out of CES today is an announcement by Game xStream that they will begin to offer high quality streaming gaming over the MCE platform for the first time. I would assume that this would fall under the online spotlight area. The offering apparently would be instant and not require a user to download games, etc.
I’m still not sure on the pricing on this but would guess that you could either pay some kind of a monthly subscription fee or possibly purchase a game outright. I would assume that much of the success or lack of success in this program would depend on the library of games that might be offered, but at minimum it might provide a nice way for someone to be able to sample a lot of the new games by streaming them before deciding to purchase.
