Could be, it was sent to me as part of a marketing pack/promo
It would seem his Stormtrooper designation begins with FN, so maybe he just makes that Finn.
I wonder if it will be one of those things where the First Order has been so fanatical with training and brainwashing that when Rey asks him his name and he doesn't know, only knows he's FN blah blah so she says 'FN? We'll call you Finn'.
This is what I've been thinking too. He may be a blank slate. That might be kind of interesting.
One thing I'm thinking about is that if finn is the one firing off that TIE in the star destroyer hanger...who's piloting?

The mission to take down the First Order is underway.
After invading the Starkiller Base, one member of the Resistance has split from her group and found herself in a massive room full of First Order soldiers. Completely surrounded by Stormtroopers with blasters and Knights of Ren with lightsabers, she seems to be totally outnumbered. Unfortunately for her enemies, though, they’ve made a big mistake: it’s not about the strength of the weapon, but the strength of the warrior that wields it.
At this point... She better be a Skywalker...
And even then... That gave me a PT chill... In a bad way.
If she isn't trained as a Jedi... How...
Ugh, I don't know. I should be more excited to hear this...
We'll see what happens I guess!
For some reason I get the impression he sounds like Droopy when he talks
None of that has been part of any rumor or leak, at no point does it seem Rey fights with a bunch of Knights of Ren and at no point does she use a lightsaber except when she finally takes Lukes.
All that really says is that she's exceptionally good with her staff. If this fight does take place then who knows? The Knights of Ren could be just a bunch of wannabes with lightsabers. Not exactly the sith.
This and also remember the majority of the jedi that were killed after order 66 was given were killed by clones. Not impossible for non jedi/sith to kill jedi.
