Re: "James Bond 23" officially slated for 2012!
I foresee a teaser trailer sometime next month or by the end of April. Not before...but I've been surprised before. We've only had a handful of set pics emerged so far after all so who knows.
The fact they've released official set pics (not shots from the sidelines like many of these) says to me they're going to be ready for a trailer pretty quickly. Or they could shoot something trailer exclusive-too (like they did with some of the Brosnan films). We'll see something with the next big blockbuster, I'm pretty certain of it. I also expect we'll learn character names for the cast fairly soon too.
