ST Lightsaber battle in Force Awakens

So we know each Star Wars film has a big lightsaber battle. Do we know who is involved in the lightsaber battle in Force Awakens? Have there been any spoilers on this topic yet?

 

One can immediately assume its Kylo vs (enter name here________________).

 

Kylo vs Finn, Luke, Rey....?

 

Luke

 

It better be Luke. If some random were to successfully wield a light saber without formal training, I'd flip ****.

My assumption is that Kylo & Luke have a history...

 

Luke versus the World Crime League

 

Hasn't this topic been covered over and over again? Wakey, wakey, mods.

 

Kylo Ren vs. Rylo Ken!

 

Anything from Making Star Wars or other reliable spoiler sites on the topic of who is involved in the lightsaber fight and what happens?

 

Just this concept art, I think.

 

Finn and Rey vs. Kylo

 

If it's Finn and Rey vs. Kylo, it might make sense that a cloaked figure swoops in to save Finn and Rey and it turns out to be Luke.

 

What if there isn't a lightsaber duel?

 

I'll leave the theater like

 

Kylo Ren vs. Rey and Finn. Luke will have a fight in Episode VIII calling it now.

 

luke vs his cave.

 

Have I gone back in time a few months or do people not read/search before posting?

 

this. i hope there is more than one battle.

 

do we know how many duels kylo is involved in?
