Action Quake II RULES!

I don't quite get it. Steam is not like the reference implementation of the 'best storefront ever' but it's not just some website where you buy and download games. You pay a subscription fee on consoles for basic features like cloud saves and sharing screenshots while your Steam 30% comission goes towards maintaining Steam Cloud, the Workshop and more. Customers get a lot of value for that. That Epic Game Store users have to crawl into the Steam forums (all paid for with the 30% cut!) to get help for Borderlands 3 is a prime example of how there's a lot of small things that people take for granted there being paid for with that cut.

So what I'm saying is you can't compare Steam with other storefronts because the feature-set is on an entirely different level.

LPDDR5 is pretty fast, running in quad-channel is a great way to get a further boost. Definitely will help the APU.
It's going to be really interesting to see how it'll run native Linux games without any of the overhead of Proton.
And there's some pretty demanding games available natively on Linux.
I expect Phoronix.com will have some must-see benchmarks to show when the Deck ships.

They said they're going to do more live service games. I don't see how this could be a Splinter Cell game unfortunately.

E:D with Horizons is pretty solid on Xbox. I don't think the new expansion would ever run on a base Xbox One though. I think they'll most likely limit that one to the One X and Series X.
I can't wait for that player-base unification to happen though.
