Good idea.
I think that MS wants to be Verizon Wireless in your living room, I think they want you to pay monthly and that ultimately the best way to get there isn't to sell you 60$ games.
Personally it's terrible for me, I do not, have not, and will not pay monthly fees for games. So this is a future I won't be a part of. I can hardly blame them for heading this way though, MMOs work, freemium games work, Monthly fees to subsidize expensive devices work. And the more non-game content they can provide the better the whole package looks.
Games as a service are here with a vengeance, so focusing on service makes sense. Smart move for them, but the end of the line for me. I feel like that old man who constantly complains about cell phones.
