Well... for suggestions, someday it would be really nice to have them there, too, but there's a huge number of them that will take a gargantuan effort to move. But having the better searching capabilities, etc, would be a huge plus.
When it comes to the bug reports on the forum, I've disabled the bug reports forum for new posts specifically because if we have a place for people to submit, they will. I don't think the bug tracker is any more complex or obscure than the forums (except by the fact that they are new), so I wouldn't expect long-term problems from that.
I do want to get public view access on the bug reports working, though...
