Its quite possible, I think, that we may never see him compete again.
He pushed himself to the limit last year. And image all the chemicals he took this year for the O, only to not compete. Man that's got to suck.
His kidneys will thank him for the rest though. Will be interesting to see if he goes entirely off for half a year or so, to let his whole body and his organs to recover, or whether he stays on to hold size and to help his injury repair. I bet he stays on some things, including test and low dosage GH throughout.
