I don't think it ever really says that he would prefer to go to Europe over the NBA. Rather he is just stating what his options are looking forward. In this case he is just saying he wants either 2 things to happen:
1. Get Bought out and return to Europe
2. Get Traded to a team where he can get consistent playing time.
This is great news for us, he is just lowering his trade value. Heck, we might not even have to give up a 1st Round pick for him anymore. (even though I'd be more then willing)
Trade James Johnson and 2011 1st Round Pick for Rudy Fernandez
