It's possible, but also (as Captain Jack would say) not probable. Only time will tell.

Frankly, I'd want their attention to be in polishing DMTNT into an as-good-as-possible POTC film rather than letting us know when a trailer will premiere. Just my opinion, I wouldn't be surprised if they have a trailer ready to go...but then again, they have PLENTY of time to show it off.
