Okay, this is just silly.
The new Mission Impossible movie is titled Rogue Nation. Paramount cleared their title with the MPAA in January, so they could have gone after Lucasfilm/Disney, but instead the companies agreed not to market Rogue One until after this summer, per The Hollywood Reporter.
Rogue Nation hits July 31; It moved up from December 25 this year to avoid… You guessed it… Episode VII. Rogue One isn’t due until December 2016.
I doubt they were going to do much marketing for the movie in any case – and an exception was made for Celebration, which is pretty much the only place I’d expect anything anyway. I wonder if this means we won’t get a filming or further cast announcement from StarWars.com, but I’m not sure what they consider ‘marketing’ in that case. (I fully expect they’ll drop it all at Anaheim…)
