If he had a severe injury issue, he might decide to play one final farewell tournament (probably the next Wimbledon available). I think he wants to go out in the right atmosphere, with people knowing he's going to retire when it's over.
I'm pretty sure he's gonna retire at Wimbledon. If not, perhaps the WTF. I don't see it happening anywhere else, not even Basel.
