I think trailers for MGSV, Yakuza 0, Bloodborne, etc are a given at this point. They're also not likely to be particularly exciting for most people for various reasons. I don't expect a release date for MGSV for example.
You think so? normally Kojima likes to tease his new trailers on twitter...nothing so far. But then again the cardboard box video at the gamescom sony press conference came out of nowhere so hopefully you're right.
