I think the conversation here should really start focusing on what we think Intelligent Systems wants to do as far as characters go. I'm assuming that, since the fans are pretty divided on which Fire Emblem character(s) should be added or possibly removed, that Sakurai probably can't decide easily either and asked IS for their input again for this game.
Do we see anything that could possibly show indication of what IS likes the best? Lyn was an assist trophy in Brawl and received DLC in Awakening. Ike has pretty much all bases covered, including DLC, shown in the SMTxFE reveal, the SpotPass descendant of him in Priam, being playable in Brawl, etc. Beisdes Ike, Marth is everywhere also.
I don't think we can really say anything about a stage revealing a playable character. That's like saying Eldin Bridge's reveal demanded a playable character from Twilight Princess, which we didn't get in Midna or Zant or whatever. We've not really seen a situation like this, so I don't think it's safe to call it, even if a character from FE:Awakening is completely possible or likely.
