tlou2 multiplayer spin off
but yeah. the ps5 reveal ought to be spectacular. i know ms bought a bunch of studios but the acquisitions were too late for anything substantial to be ready at launch. this is where sony is going to win.
~2 years is plenty of time to get new projects going. If they show well at E3 then that is good enough even if they need more time in the oven. I think the much bigger issue is quality. Halo Infinite is probably a launch title and in the past that would have been beyond major. Nowadays however it might function more like Killzone Shadowfall.
