New Seasons on the way?

I haven’t seen anything on a season four coming, and it has been longer between now and three than it was for the other seasons. I have nearly 20k points I’m sitting on in hopes of new weapons and key options. I don’t care about having a green version of the same costume or a different head that I can’t see in a FPS. Are future seasons coming?

Bummer. I wanted to buy more weapons.
