Now after Disney's announcement of new Star Wars movies, the hush hush nature surrounding Into Darkness is falling down.
Unless Episode 7 has been moved to a Summer 2013 release without my knowing it - I doubt it. The marketing for STID has and will roll out as scheduled without any consideration of Disney's announcement.
Look at them objectively. What do we know about Star Trek Into Darkness?
We know it's a sequel to ST09
We know the protagonist cast
We know the writers
We know the director
We know the actor who only recently has been confirmed as the villain.
We know the synopsis of the film.
We know it's nearly finished production and it's release date.
What do we know about Star Wars VII?
We know it's a sequel to Ep VI
We know Harrison Ford, Carrie Fisher, and Mark Hamil have all met with Lucas on potentially reprising their roles.
We know the writer
We know the director
We know Disney has the film in pre-production and has a release date set for 2015.
Besides already having and established production and head start on filming and casting, what else do we the general public know about Into Darkness? Nothing. Star Trek XII has been cloak and dagger throughout it's entire production. Even though we have known it's coming down the pipeline for about 4 years now all we know is vague details. In one month Star Wars has been able to generate bigger waves through Hollywood and across the internet than Trek has.
You can't deny and even TPTB couldn't deny that they've been feeding tidbits and crumbs to the general public. Unlike something as big as DKR or Avenegers where the general public en masse was excited for there release and they were given trailers, and pictures about the upcoming movies. Also the actors and directors didn't shun people in to the quiet zone (Like JJ did to Karl Urban when he talked about Trek prior to comic con this year). Hell the actors, and directors were as forward as the could be without spoiling their movies. Meanwhile only people keeping Trek's speculative fire alive are we the fans. General public isn't pining away for the next Star Trek film like they are for say The Hobbit for example.
The synopsis dump seemed like Paramount was worried they'd fall in to obscurity since they've been so coy with their upcoming feature. The Star Wars sale to Disney and announcement of more films caught everyone by surprise. Paramount releases the synopsis as a red flag to a bull "HEY DON"T FORGET ABOUT US!!!"
