in order:
pettis vs gil (competitive, most entertaining fight compared to the other title fights imo)
jones vs DC (competitive fight, DC will shock people imo)
cain vs werdum (competitive, even though most wont agree... great matchup stylistically, people still doubting werdums striking)
weidman vs belfort (the least competitive fight since vitor is off TRT)
dillashaw vs barao & aldo vs mendez tied (i dont like rematches, both of them are competitive fights though)
man, all of these title fights will be highly competitive.
there could be many different champions come 2015
Predictions:
pettis
DC
werdum
weidman
dillashaw
aldo
