I just don’t see much of these existing games switching over to SR6 in a hurry. I mean sure, someone will run an SR6 game (just like we had an Anarchy game). There is so much depth and breadth in 5th at this point (along with, and hidden among, all the editing oddness — but we are at least used to the existing editing oddness by now) I think it would be hard to switch over in the near term to just a CRB based game for one of the ‘main’ games.
I guess we’ll all get a better feeling once we see the new CRB.
