Why wait? Haye has won his title at cruiser there are no big fights left for him there and very little money when compared to heavyweight.

David Haye (if he's as good as they say) will do very well in the division and causes for some interesting matchups.

I for one would like to see Haye vs the following: Sam Peter, Nicolay Valuev, Sergei Lyakhovich, Tony Thompson, Eddie Chambers, Alexander Dimitrenko, and hell anyone in the division, of course he'd have to start out with someone like Guinn or Timor Ibragimov and work his way up safely but after 1-2 warm ups he could jump into the thick of things
