I'm real interested to see how they are going to treat the character of Woolsey on SGU...
His personality is a total clash with the other characters on the show. Depending on who he will be interacting with, we could get to see another side of the man.
Hopefully he is going to be closer to his SG1 personality than his SGA one - I'd love to see the showdown between Woolsey and Young when Woolsey learns of some of the stuff Young did.
It's a shame they won't make him a regular (if the show was to continue (which is now more and more likely!)).
