Kylo Ren who has spent the last two movies killing old white men:

So the last thing we hear Luke say in the trailer is 

“No ones ever really gone.”

with this scene being played underneath it

Now obviously this is the DeathStar, and with the laugh that plays during the title reveal its clear that they want us to think that Palpatine is back. (Which I do believe is going to happen but thats not the point.)

Palpatine:
