I think there is definitely going to be a third somewhere down the line. The way Tito and Forrest spoke about the fight, and the way that both fights were close decisions, I think the UFC would like to push for a fight which decides the series.
It won't happen for a while though. Probably early 2011. There are rumours that these two might coach the next season of TUF so the UFC gets to market the fight for a good few months through that.
As long as it wasn't the headline fight or even the co-main event I'd be happy to watch it.
