It seems some people are struggling to believe that the video shown off at E3 for Resident Evil: Revelations on 3DS was FMV or not actual game footage. Capcom have come out and confirmed that it was in a PR email:

“Following last week’s announcement that Capcom currently has two titles, Resident Evil: Revelations and Super Street Fighter IV 3D Edition (tentative title), in development for the Nintendo 3DS. The first trailer for Resident Evil: Revelations has just been released and is now available for download from our press extranet featuring appearances from Chris Redfield and Jill Valentine the trailer is rendered in real time using the game engine.”
