Serious amounts of salt.
Sure, MS games shown have release dates. But 95% of the games were announced a while ago. So.....you just show them again when the release date is finally around the corner, and then say "hey, our conference is fine. At least our games are coming out soon"?
Yea, because you have nothing new to show. Sony, on the other hand, showed us future games, because they had no need to show us current games that are coming out this year, because they're with the program. They already showed No Man's Sky, GT Sport, Gravity Rush 2, Persona 5, Paragon, Star Ocean 5, King of Fighters XIV, World of Final Fantasy, etc. and they all have release dates. They showed that last year to let us know what to look forward to this year. What would have been the point of showing them again, unless they didn't have a release date prior (ala TLG)? What did MS show to get us interested in them for the future, since we already knew games like Gears 4 were coming this year? *crickets*. Oh, and not to mention, SFV, R&C, and Uncharted have already released this year. So they've already released 3 big games for 2016. What has MS released? *crickets*
The bludgeoning that Sony doled out, in comparison to MS, would have been even worse had they included all those games, if we're playing by the MS rules of "show games we've already announced years ago, but glorify that they have a release date that's soon"
