Well, offering my opinion, though I'm sure no one wants it.
1) Tim seemed really uncomfortable going into Wimbledon. He was complaining about everything. Pulling a Hewitt as I call it. During the match, he started complaining about the ball kids. I don't think that he ever really felt comfortable at Wimbledon this year.
2) He played poorly and inconsistently.
But I have no doubt in Tim. I do believe that he'll win Wimbledon. (With Justine no less), and that he'll be back. No one said destiny was ever easy.
