Seriously, look away!
So, here is what I've heard, summarised...
1) The next film will involve Khan as the bad guy.
2) Khan will be played by Benedict Cumberbatch, who you may know from the recent "Sherlock" series.
3) The Klingons will also feature
Regarding Khan... well, I'm not sure it's a good idea to go there. Comparisons will inevitably be drawn to Ricardo's Khan, who is perhaps the single best-regarded villain in Trek history. But then again, JJ has not shied away from having big boots to fill. After all, he recast Kirk and Spock and McCoy and the rest, and not only got away with it but did a pretty acclaimed job of it. So he's clearly willing to take on those kinds of challenges and has so far shown himself up to the task, too.
That said, Benedict Cumberbatch? This guy :

As Khan, of all people? He doesn't convey the physicality I would have expected from the "genetic superman". Nor does he look the least like the Asian warrior. I guess the magic of genetic engineering can be invoked to make a relatively slender guy ten times stronger than any muscle man, but I do wonder how that will sell on the big screen. Or alternately, I wonder if they will go a different route, and make Khan a much more intellectual enemy for Kirk. Will we get a story of ploys and tricks and manoeuvring?
Also, you have to wonder about the whole timeline aspect. I can buy a different actor as Khan without resting to "it's alternate" as an explanation - after all, Chris Pine doesn't look like a young Shatner, so there's no real reason why Cumberbatch needs to look like a young Montalban. But if they are going to change Khan's characterisation radically? If they are going to alter his back story? Change the Botany Bay significantly? What do we do to explain that? Push the branching point back, in direct contradiction to the previous film? Or just admit that the last two films are a total reboot, nothing to do with the original, and get over it?
Regarding the Klingons, from what I have read their part has been described as "one not easily cut from the film". Which makes me think that they have something significant going on in the film, but not all that significant. I will be intrigued to see what changes, if any, JJ goes with. Will he change their look yet again? Will he change their culture? Will they be allies of Khan, opponents to him, or players in their own right?
Lots to wonder about...
