June - Train in Bay Area
Early July - Train with Olympic Select/Olympic Team (If he signs a contract by the start date)
August - Summer Nike Tour of China and Taiwan
Sept - Back in Bay Area
Oct - Start of NBA training camp
My guess is he'll also probably train a bit in Vegas at Impact, and play pick up in L.A. and at Charity events like last year.
Also, I found the interview with Jeremy talking about winning a Gold Medal back in 2010 before he even played a game in the NBA: Jeremy Lin #17: Gold Medal for USA?
