Sony: impossiburu, I cannot imagine a scenario where they can fail to deliver lol
Nintendo: by focusing only on 2017 titles and predictable games: Mario, Splatoon 2, Pikmin, ports like Smash 4, MarioMaker etc. I want some hype stuff like Wonderful 102, Mario Football 3, Luigi's Mansion 3, Diddy Kong Racing 2, BEYOND GOOD N EVIL 2 etc
Microsoft: I give them 5% chance to impress me, have the lowest expectation I ever had for any conference ever so I dunno how they could manage to do worse. It can only go up for me with this one.
By not showing Death Stranding, Red Dead, TLoU2, and not announcing Sucker Punch's new IP. And also have bad showings for Days Gone and Detroit (and not giving it a release date)
Brah those games are very likely to be saved for PSX.
