Menu and Online Multiplayer Walkthrough Revised

Do you all think it's a good idea if A.I. bots filled in the rest of the spaces when there's not enough online players to fill in all the spots?

From what I heard from here, (I don't own a PS3) the AI was significantly improved, so do you think it's a good idea?
