My guess is that the trailer will contain most or all of the footage in both the English and Russian featurettes, including the footage displayed behind the cast while they're being interviewed. In addition to that footage we might get a handful of brand new shots. And to fill out the rest of the 3 minute trailer duration, we'll get footage we're already all familiar with.
I'm really curious to see this new trailer and I'll be extremely disappointed if it's just an English version of the Russian featurette because this was being advertised as a trailer.
If we do in fact get a new trailer, mark my words. There will be at least one shot that will cause a huge reaction. I'm guessing we will see a glimpse of something but only barely. Since they'll be broadcasting a few twitter reactions in the next break, I'm sure they will have a treat in store for us.
I just hope that this one will make its way online in HD.
I remember during The Dark Knight campaign, there was a trailer that was released as part of a Pizza Hut tie-in (if I'm not mistaken) and that was my favourite trailer. Too bad that it only ever saw a dark, low resolution release.
