There is a big chance, that sections of Sony's conference will fall short -or "miss" the wow effect.
Here is why.
Star Wars: Battlefront: Gameplay will likely debut at EA's conference hours before Sony's
Uncharted 4: A Thief's End: Gameplay was already shown at PSX last year.
Assassin's Creed: Syndicate: Gameplay was already shown a few weeks ago.
Destiny *Comet: Destiny has appeared on way to many Sony press conferences. Some want it, some doesn't.
Project Morpheus: Not "game" related. I am afraid it will be too much PR talk.
Fallout 4/Mass Effect 4: Should either of these games appear, then they would have already appeared on other press conferences.
Street Fighter V: Again, we have already seen it in action.
