User blog comment:GinIchimaru/596 - Sabo's return imminent?/@comment-2031609-20100819195641

Yeah, I'd like to see Sabo alive too, but DancePowderer has a good point... The only argument I could see to that would be that Sabo is alive with the Revolutionaries and never got back in contact with them since he doesn't know they think he's dead and expects them to meet at sea. Also think about how Revolutionaries, for the most part, only contact other Revolutionaries. Only the higher ups know where Dragon is/how to contact him. Kuma is an exception because of his Shichibukai status. Ivankov and Inazuma only allied themselves with Luffy because of the situation and his relation to Dragon. So one could conclude that Sabo could be alive, but simply didn't contact Ace or Luffy.
