Here's my opinion based on the facts as presented thusfar (you're welcome to disagree): the pictures of JJ sitting at a console was taken at the time of the web chat, which means it was taken while they were filming on the Enterprise bridge. What you see in the pic is a station on the new Enterprise set. It isn't a 24th century ship. It isn't an alien ship. That's the Enterprise.
So, having said that, does it look anything like the TOS bridge? Well, not really, but the picture is so vague and washed out and lacking in detail. There's no way to know what the entire set looks like. But so far I don't see a bunch of bright primary colors and massive jeweled buttons. So what does this mean? It means that this film isn't going to be a literal re-creation of TOS. It's a "re-imagining" if not a "re-boot". It makes perfect sense to me - I honestly don't want to see a re-creation of TOS. The sets, costumes and props as depicted in TOS are simply outdated by today's standards. It wouldn't hold up to today's audiences (except for Trek fans who are TOS purists, and that isn't JJ's target audience).
