Counting presentations and trailers, yes, it's absolutely true. Sony showed:
Beyond: Two Souls
PlayStation All-Stars Battle Royale
Assassin's Creed III: Liberation
Assassin's Creed III
FarCry 3
Book of Spells
God of War: Ascension
The Last of Us
Although several other games like Dyad, Papo & Yo, The Unfinished Swan and Diggs Nightcrawler were just namechecked, with no trailers or live footage shown.
Microsoft's exclusive games were:
Halo 4
Fable: The Journey
Gears of War: Judgment
Forza Horizon
Nike+ Kinect Training
Ascent: New Gods
LocoCycle
Matter
Wreckateer
Dance Central 3
There were a few interesting titles in both conferences, in my opinion. The Last of Us and God of War: Ascension looked great, and Beyond could also be good, although I was hoping for something more original.
They also announced they've acquired another studio,
Press Play.
