I always end up being disappointed with these things, so I'll set the bar low and tailor it after the tapestry of past E3s:
-10 minutes of sales charts, "man on the street" videos of people saying things about Playstation because someone with a camera told them to, and masturbatory back-patting.
-5 minute "exclusive" demo... of a multiplatform game we've known about for awhile... that doesn't demo well.
-5 minutes of PS4 sizzle reels for things we already know about and a couple things that might have been surprising if they didn't leak the week before E3.
-Infamous DLC reveal, looks pretty cool but eh it's a DLC reveal.
-2 minute indie reel for things we've already known about but occasionally may not have known were coming to PS platforms. 3 additional minutes of Sony buttering up indies. High possibility of Shu video/Mega64 video for laffs (Laffs not guaranteed).
-Kojima comes on stage for a few minutes and demos MGS5's equivalent to watermelon cutting and wraps up with "60 minutes of exclusive gameplay, Only on Playstation" non-bombshell.
-5 minute demo of an actual exclusive that we already knew about but haven't seen much of... Looks really pretty, doesn't demo well.
-10 minute reveal of an actual new game that's 1 minute trailer, 9 minutes guy on stage giving a sales pitch/recounting why police traumatize him and then telling us to look forward to it in
early late 2015
-20 minutes of blah blah about Project Morpheus intercut with copious amounts of Media Molecule and/or Quantic Dream noodling around on tech demos.
-5 minutes of PS3 talk and a sizzle reel of stuff we already know about.
-2 minute sizzle reel of Vita stuff we already know about; Maybe,
maybe one mild surprise like a new Patapon or Locoroco or something.
-That's all, folks!
-Just kidding, third party surprise reveal (Potency of surprise not guaranteed).
-Okay really now, get out.
