Where Can I Rent Games?

Now that Blockbuster has died where do people rent video games? I mean, I know about Gamefly but if the game is new and popular it seems impossible to get it within a month. I know Redbox offers some titles for $2, but it's very slim pickings and availability is an issue. So what's left? Also, with all that's developing in the gaming industry does game renting have a future?
