I'd love to see:
Fedor (confirmed)
Charles Bennett
Arona
Sokoudjou
Sakurai
Minowa
Sakuraba
Aoki
I really hope we get to see all the pride stars back in the ring and with pride rules! The match ups are endless! 
I think you should also take it as a given that McGeary will fight Phil Davis on that card.
Other than that, I'd love to see a great opponent for Fedor either in terms of fighting skills (Arona) or in terms of marketing (Brock, Kimbo).
I think a fight between Fedor and either Kimbo or Brock, plus some Japanese star in the earlier fights will sell at least 40,000 to 50,000 seats in Saitama if it is marketed correctly.
Kron
I submit cats - KronWould be a great place to debut!
I'd like to see Rodger on the card as well
Tom Erikson!

Agreed.
After seeing Mayhem beat the hell out of him, I have no interest in seeing him back in the ring/cage. It's not worth it for him to take the damage.
Isao Kobayashi vs somebody good from Bellator at 145 or 155.
Georgi, Chandler, Patricky, Goiti Yamauchi or whatever his name is, idk
Rickson VS Takada 3 Please
