They've said PS3 patch will probably not come until PSN is back up - They want to patch lag issues at the same time, if there are any, but they won't be able to find that out until we can play online.
In the meantime, your best AI fix is to play on Hard. Which gets mixed results - when I do it, friendly bots are still idiots, but FAR less so than the other difficulties. Some people have said it doesn't work though.
