Running on vapors? I highly disagree. There's lots of gas left in his tank. At least enough for a couple more years, so this year he should still be throwing heat. I can't see him having an ERA north of 4.
I say 15-10, 3.80 ERA, 190 K's, 1.15 WHIP. Maybe a bit optimistic, but the 'Stros have a good offense, and this move might rejuvenate him.
