It's funny to see tons of people's dreams crushed when the real show doesn't match up with their expectations. Come on, guys, how many times are you gonna fall for the same thing. I'm rarely disappointed because I hope for a lot but expect little. For example for this E3 (Just Sony's 1st party games and marketed games):
What I hope will appear:
Uncharted 4 gameplay
Horizon reveal
The Last Guardian re-reveal
God Of War 4 teaser
Sony Bend's new IP
No Man's Sky
Batman Arkham Knight launch trailer
MGSV trailer
What I actually expect:
Uncharted 4 gameplay
No Man's Sky
Batman Arkham Knight launch trailer
MGSV trailer
This way, you won't be disappointed
