I would hope that Destiny 2 would be so new and different that it wouldnt make sense to import old characters. They have a chance to completely wipe the slate clean and start over with a fresh story, new classes, skills, gear, etc. For example why even stick to our current solar system? What if people had escaped our solar system and found something new and more interesting than the traveler and a new place to colonize that is now being threatened by something other than the usual taken, fallen, etc. You could have cameos from the original. For example maybe someone in the new story knew Cade prior to the collapse or maybe some of our favorite weapons were recreated with some new twists for this new environment. Basically put, if Destiny 2 is so unimaginative that it makes sense to carry over my current stuff then I may need to keep looking for a more innovative game.
