If I had to end my games, an epic battle would probably be the way to go. However, when you're half way through Age of Worms and Shackled City, Red Hand of Doom, and started in Rise of the Runelords, I just don't see all these games ending just for the sake of the new 4e system. So, no I don't think my games will end. Doesn't mean something 4e won't start up as well, but the 3.5e games will continue, and I have my reservations about whether the gaming group is interested in 4e.
