Condit is my favourite fighter and I thought he won the last round but that fight was 29-28 to Hendricks all day - and a decent argument could be made for 30-27. You don't win a decision by shipping 12 takedowns in 15 minutes.
I'd take Condit in a 5 round rematch though.
As for Hendricks vs. GSP, GSP has faced power punchers and fantastic wrestlers before and not been too troubled. Hendricks however has not faced anyone as defensively sound as GSP, and I think that will be the difference in this fight.
