Many people were predicting multiple SOP events scattered throughout the next few months to reveal multiple titles. Same people were saying the same thing even last year.
However I've been saying for months now that it's simply not Sony's style to miss out on a huge blowout event in which they can potentially reveal some BIG titles. Sony are divas, they want all the attention, glamour and eyes they can get, just look at their previous events in the past year or two and look at the amount of views they've garnered, it's insane.
