That’s as unambiguous as you can get – right there in the trailer, Deadpool forms and names “X-Force.”

And really, if you’re going to do Cable, aren’t you practically obligated to do X-Force along with him?

You can’t always completely tell from a trailer, but it sure looks like things haven’t changed a great deal with David Leitch taking over as director.   The action might be a hair crisper, but this sure seems like it’s primarily plugging in a few more Marvel mutants into the last film… which is pretty much exactly what most people were looking for in a sequel.
