I think we can all rest assured that however IWTB's boxoffice take ends up, there will eventually be a third movie. Popular franchises are always a somewhat safe bank for studios, and if you consider that other franchises (Batman, James Bond, Alien, Star Trek, etc.) have all had their misfires, they all continue to this very day. So will the TXF. Hell, they're even doing a new Beverly Hills 90210 TV show... In some way, TXF will return, even though I suspect we're going to have to wait for it until the inevitable 90's revival will take place.
