I do kind of have a faint dread in the pit of my stomach that Sony may be showing all this stuff pre-show and then re-tread through it during the press conference. For example anything R&C related, if at the conference, would better have been left for the show to make a more exciting first impression.
If half their content is just showing all this stuff we've seen the past week, that would be a big misjudgement on their part. At least in my opinion.
However, if they are clearing the way so they can have an announcement packed conference full of unannounced games then i'm all for it!
