Yep, the art does not fit but it could be a capture from a CG trailer. If that's the case, that would be weird. I'm waiting for this game and all but a CGI trailer now? You either release that kind of trailer to announce a game or for its release as a launch trailer not in the middle of your marketing campaign. Still I'd would watch it with pleasure.
Well, to be fair, the campaign doesn't look to have taken off just yet. We've seen screens, a few interviews and heard about some features but I suspect we'll see a lot more around E3 this year. Press demos, maybe some supporting gameplay trailer (seeing as we've now seen the CGI trailer) and (hopefully) an indication of a release date. I'm guessing end of year although that it looking pretty packed already. With the US elections, ad space is going to be really expensive and we're still seeing AC3, Bioshock Infinite, CoD and other major titles release around then. So maybe they're looking to fill a slot in early 13. Still, Skyrim had 11-11-11 so Bethesda could go for something in that week, I guess.
