Who is Finn?

[Loklorien s'Ilancy]

I've heard a few postulations that Finn could be a Calrissian, or that he even might be kin to Mace Windu. After seeing the most recent teaser that McBain posted, I have to wonder if Finn could indeed be a Windu.

Anyone else have guesses or theories about Finn?

I think he's.... a Force sensitive Stormtrooper who drives the plot of the film!
