the whole rhaegar + lyanna = jon theory, my only big question about this is... who alive actually knows this? Who's going to be able to tell Jon that he's actually a Targaryen? The whole Rhaegar and Lyanna relationship had to be pretty secretive in the first place, so who was entrusted with this knowledge, other than Ned? And if nobody other than Ned knew, who did Ned trust enough to tell? Benjen maybe? But if that really was the case, why would Benjen want Jon to join the Night's Watch, surely he'd know that he'd be destined for greatness? or maybe it was a protective measure. But the real question, who's actually CREDIBLE enough to where the "Jon Snow is really Rhaegar's Son" announcement is actually going to matter? Nobody would believe it, and what type of problems would that create between Robert's supporters, and Stark followers when it turns out that Lyanna was an adulterer with the ENEMY. i don't know, i'm inclined to believe the theory, but it seems like it'd be incredibly difficult to pull off correctly.
