Not necessarily. I don't agree with it, but I can understand their rationale to an extent. It's designed so that new and exposure on The Order is released in stages, to keep the game being talked about beyond its initial showing.
Stage 1 : show a short trailer + teaser at keynote = get people talking about it.
Stage 2 : a larger playable slice on the showfloor, showfloor impressions or quick-looks from sites that are on-the-ground at PSX actually writing it asap, with some cuts.
Stage 3 : news/previews start trickling out from sites that got preview code instead of playing it at PSX.
Chances are stage 4/5 will have something similar to inFamous:SS, where we'll have the media being allowed to stream the game, or select media outlets will stream it with RAD alongside to talk about the game and their ideas/PR management during the stream itself.
