You'd have to think a rematch is on the cards, wouldn't you.
Regardless, there's a bunch of interesting potential fights at 205 now.
Just about any combination of Griffin, W Silva, Shogun, Chuck, Rampage and Machida would be pretty tasty. Add Vera into the mix if he's serious about dropping to 205 full time, and maybe (though it's probably unlikely) Anderson Silva if he deals with Irvin and feels like there's nothing let to make it worth hanging around at 185. Should be an interesting next few months.
Even if Irvin wins, he might get boosted into the top ten as well! He has huge power.
I think the rumor right now, other than an immediate rematch, is that Chuck will fight Rashad for a title shot. Rampage will fight Wanderlei. Machida will fight Thiago Silva. Shogun won't be back until later this year. Vera is fighting on the July 19th card. Sokoudjou is not fighting anyone either.
I think that Rampage should get an immediate rematch because I feel that no other top contender is worthy of a title shot as of yet. Let's take a look at the contenders:
Lyoto Machida 13-0 (5-0 UFC)
Notable Wins: Tito Ortiz, Rameau Theirry Sokoudjou
Has going for him: No one wants to fight him
Lacks: Wins against top five competition (Rampage, Griffin, Shogun, Wanderlei, Chuck)
Needs: Top Five Fight
Chuck Liddell 21-5 (16-4 UFC)
Notable Wins: Tito Ortiz, Randy Couture, Wanderlei Silva
Has going for him: Arguably the most popular MMA fighter as well as friends with Dana White
Lacks: A winning streak since losing the title (1-1 since losing the title)
Needs: To return to championship form with a KO (two decisions since losing the title)
Wanderlei Silva 32-8-1 (2-3 UFC)
Notable Wins: Quinton Jackson, Ricardo Arona, Keith Jardine
Has going for him: He owns the former LHW Champion "Rampage"
Lacks: A winning streak (1-3 including the OWGP semifinal)
Needs: To have a strong win in his next match with whomever it may be
Quinton Jackson 28-7 (2-1 UFC)
Notable Wins: Chuck Liddell, Dan Henderson
Has going for him: A great deal of people believe he should still be champion
Lacks:
Needs: Dana White to give him the rematch many feel he deserves
Mauricio Rua 16-3 (0-1 UFC)
Notable Wins: Quinton Jackson, Ricardo Arona, Antonio Rogerio Nogueira
Has going for him: People still consider him the best when healthy
Lacks: Credibility with American fans and a winning streak
Needs: To get healthy because he can be the best fighter at still a young age
This is my analysis of the top contenders. I really think none of the other three are ready and Shogun is injured still. I don't know what's happening with the UFC because a Wanderlei-Rampage rematch could be bank. I just don't think Chuck is ready for a title shot and neither is Wanderlei. I've already expressed my opinion on Machida. Heck, if you want two guys fighting for the title shot, make it Rampage and Machida. I just think Rampage deserves an immediate rematch.
