They had one along with a cutaway 6.7 diesel at a local car show a couple weeks ago. It was all locked up and the hood was shut so you couldn't see too much, but it was badged as a Powerstroke and still had the stupid looking dual exhaust tips (still better than the GM blunderbus exhaust tip)
Pictures don't do them justice, they look much better in person than the released pictures show.
The 6.7 is laid out much better than the 6.4... much better. All of the more common diesel repair stuff (EGR, turbo...) is on top of the engine and no longer requires the cab to come off to replace. All in all, it seems to me so far that it is probably the best thing that happened to the line of trucks in quite awhile... just by looking at it. Kinda got the vibe that Navistar laid out their engines how they wanted to and Ford had to try to adapt their trucks to fit the engine, now they can both be adapted to each other rather than one getting pulled out of a flipnose and stuffed into a pickup cab.
If you have a big carshow with the new cars somewhere local... I bet it will be there. The one that was in Omaha was a travelling car show. They also had the new 5.0 Mustang there as well (also shut up tight though)
