I'm loving the photoshopped title cards! :-D
I still don't think this is the actual title, though. Again, Abrams and co. are not stupid; they know there are people out there who pay attention to things like domain names. (Witness the '08 elections; people looked to see what domain names had been bought [obamabiden.com, obamaclinton.com, obamarichardson.com, etc.] to try to ascertain the final pick.)
And the fact that they haven't commented on it yet makes me even more convinced that this isn't the final title. They gain nothing by waiting, and they just look bad by delaying it.
My take: "startrekintodarkness" may be part of an advertising gimmick for a differently titled movie. Though, more likely, in my opinion, is that the movie will actually just be called "Into Darkness," but that they wanted the domain name to have Star Trek in it, for various reasons, not the least of which is to make it easier to find through a search engine.
This sets up a trilogy nicely, title-wise: Star Trek, Into Darkness
and then something like "New Day Rising"
I finally watched Sherlock's second episode of the second series and in it Watson calls Sherlock (CB) "Spock" because he's emotionless. Is this a tip as to CB's character? Will he be a renegade Vulcan? Is he going to interfere with old Spock's efforts to unite the remaining Vulcans? Will old Spock work toward reunification with the Romulans but CB's character is against this idea?
You have good taste in British television.
As much as I like this idea, though, I don't think it's what's happening.
