skyjedi2005 - I wouldn't worry about the fact that we might not see much of Mark and Harrison on this thing. Usually Justin fails to ever get a 're-union' of any specific show members he goes after! It's usually just a case of being lucky enough to 'hang out' with the 'more accessable' ones on an individual basis, and reminisce with them on a personal level. It should still be a warm and possibly irreverent watch. Enjoy!
