Most of them will, and sadly the stickies will as well. But who cares? No one reads them before posting, even though they would probably find their answers much faster if they looked around first before posting.
In a nutshell, there's a thread on the Forums' status when AG3 comes out, read it first.
They probably won't even migrate anything since in that thread it states that it's going to be very difficult for them to migrate stuff. So expect cleared out forums. And it's not even an important thing for the site since the amount of forumers is very low.
