I hope we see Hellblade II sooner rather than later; it would suck if we have to wait til around this time next year to see gameplay. It's absence was my biggest disappointment.
That one has the potential to be my killer app and sell me on the XSX.
If I had to make an estimate right now, I'd say they'll show Hellblade II gameplay at E3 2021, and plan release for mid-late 2022.
Everyone is giving Xbox flak for lack of gameplay now, but E3 2021 will be the most important event of this gen, just like the E3 2014 hype storm basically carried PS4 through this gen.
Halo Infinite is meant to have Xbox hit the ground running, but it's having a few hiccups. It still makes sense for MS to focus on getting that ready and showcasing it, as it'll be that and most likely Forza Horizon 5 later as the year one titles for the system.
Even though they haven't done a great job showcasing 'next-gen' yet, I'm glad they're at least prioritising games that'll be playable in the near future.
