no sony bend, no Media Molecule, and possibly no Guerrilla Games.
Shinobi has said GG might be there depending on other stuff and they already got the trailer ready. Either we are gonna be pretty dissapointed in Sony's first party at the show, or Sony has quite a lot of surprised, and the show doenst need bend, MM or GG to be "jam packed".
That's the same reasoning MS fans use lol. Except I'm pretty sure the Halo and Forza devs + Insomniac will be at E3 despite the earlier reveals
