Word is the main reason he wanted out is to spend more time with his daughter. And after spending 8 years on a show, I can understand that. I'll miss him, I've been a RDA fan since day one of MacGyver, so it's going to be weird to not see him on TV in fresh stuff.
Amanda Tapping (Col. Carter) will be missing for a few episodes (left overs from her having a baby not too long ago) as well but she's definately back this season.
