Martinez by KO or Norris by decision would be the safe bets. The former seeming more likely with the knockout victories of Williams and Dzindiruik fresh on the mind. I'd like to see more of Sergio against quality boxers before picking him in too many mm's though. I don't see him as overrated as some do here but he's only recently established himself. (albeit in impressive fashion)
could go either way, and Martinez has been hurt by lesser offensive fighters than Terry Norris... dont underestimate that one, undeniably potent aspect of Norris' game. Obviously, Norris is vulnerable as always
