Haven't seen anything reported we'll have to wait for some of them to take delivery, probably around the same time owners do, after that give it about a few months till we see what ever they want to show us.
Might be best to keep an eye out on social media pages and websites of aftermarket companies more likely to come out with one.
from the way it sounds on youtube through fast lane truck there is a front bumper that can be ordered from the factory to support a winch. not sure what size though. if you look up ram rebel, the fast lane truck, and the video is about 11 minutes long. about two minutes in he does confirm that mopar has one for it already just has to be ordered. I would be sure to expect a steep price for it though.
Im pretty sure TFL truck said that Mopar confirmed there is room for a winch (ala power wagon style) but that it wont work with the stock bumper and you would need to modify it OR get a custom bumper, not that they have one available to order.
