Dave Meltzer thinks we're going to see a rematch:
The decision will be based on a number of things. Among the questions are who will produce the best box office (likely Silva); what will be the most exciting match (hard to say as both matches were exciting but based on first encounters, the edge goes to Silva); and what win will mean the most in selling people on the idea the old Liddell is back (again the edge is to Silva). The other note is that with a Silva match, there is a definite place to go next. A Jardine win would knock Liddell out of contention and out of money matches, and would set up Jardine as an opponent for the Jackson-Griffin winner. A Silva win would knock Liddell out of contention but set up two possibilities: a third Liddell-Silva match or Silva challenging the winner, particularly Jackson, since Silva beat Jackson twice in Japan.
Frankly I'm down for this. I really dug the fight and I'd like a conclusive finish in the rematch. If they could make the rematch a 5 round fight I think everyone would want to see it. It's really more appealing than Chuck/Rashad or Wand/Jardine.
