Who is more likely to return to the Astros?

The Astros just lost 2 long time players that were cornerstones of their franchise.  I think both wouldve liked to finish their career in Houston but i also think both wanted a shot at one more title and i cant fault them for it.  Both seemed to express interest in possibly coming back to Houston before they retire.  Berkman has always lived in Texas so i imagine he'll want to come back as soon as he can.  Oswalt is still 1 win away from the club record and i really think he wanted and wants to break it.  If i were voting on the poll, i may be on Oswalt over Berkman.  While Berkman has more ties to the club with his hometown, he plays a position that has been filled by Brett Wallace while Oswalt plays a position that has 5 spots in a rotation.  I think Oswalt has a little more incentive to come back with the club record in wins still in reach.  What do you think though?
