Please don't bring out Sakuraba, he's done. But if they must, have him fight another shot fighter like Ken Shamrock.
Gomi-Penn? Been there, done that. Let's see something new.
BTW it's great to hear they are collaborating with Dream and Sengoku. UFC is never going to put on as many shows in Japan as those guys are so the UFC can't take over that market, you might as well work with them and share fighters. I'm sure the low and mid level fighters in UFC would like to get some more fights in, this provides another outlet for them.
