Who do you want to see the Klitschkos fight in the coming year 2012? In my opinion, Wlad should fight Arreola in the early spring, Thompson in the summer, and in Nov/Dec 2012 he should fight whoever of these three are willing: Fury, Povetkin or Helenius. And Vitali should fight Dimitrenko, Stiverne, and Wach.
Wladimir should fight Thompson in the Spring, then try to get a mega-fight with Povetkin for the summer. Hopefully by Fall 2012 a new major contender emerges (possibly RH). Vitali should fight Valuev if possible. Otherwise, try for Haye. If not them, then go for Povetkin or Chagaev or Pulev. This is all in the realm of "should". In reality, Wlad's Spring fight will probably be Arreola (very easy) and Vitali's Spring fight will probably be Dimitrenko or Huck (even easier). Stiverne doesn't deserve a shot, but if Vitali is focused on politics this might be an easy stay-busy fight for him. Wach is an impressive prospect but he should fight an eliminator before getting that K2 paycheck.
I wanna see Vitali vs Stiverne, just for the fun of it (how many jabs can Vitali land in a row without anything in return?) And also Vitali vs Povetkin to screw over the crooked WBA (how are they going to handle that one?) For Wlad I see Arreola as a nice opponent, and the onesided asswhooping called Wlad vs Fury (Wlad can then claim a KO victory vs Tyson within 3 rounds)
Helenius & Dimintrenko are the only contenders that wouldn't make total fools of themselves. The rest are just canon fodder.
