This should be a great show, especially since it's free. I think Henderson will beat Rampage, but it won't be an easy match. I really don't think we'll see another first-round downer like we did in Rampage vs. Liddell, but I don't see it going five rounds, either.
CroCop will destroy Kongo. In the fights I've seen Kongo has used his strength and size to push his opponents around a bit, but his technique is very shallow and full of holes. I think CroCop is big enough and hits hard enough to neutralize Kongo's muscle without much trouble. Plus CroCop is coming off a humiliating KO, so he'll come in looking to redeem himself in spectacular fashion.
I don't really care about the Bisping Hammil fight, but it would be interesting to see the crowd deflate after watching Bisping take a loss on his home turf.
There's also the Alexander vs. Sakara fight to look forward to, just to see what Alexander can do after completely destroying Keith Jardine in his last fight. Some people have been claiming that he'll be the next champ, but I think he still has a heck of a lot to prove before he gets anywhere near a title, especially in the ridiculously stacked Light Heavyweight class.
Remember, if you're planning to watch the fight on Spike on Saturday night you'll want to stay away from MMA or sports sites that day, since the fight will be shown on tape delay due to the time difference.
