What are the specs of the Atlas chip? Have those even been released?
Looking at the comparisons between Orin and the Tegra X1 Maxwell I'm sure they'll go with Orin. It's 7-8 times more powerful and that is a generational leap for a console. If they are smart they'll repeat the hardware decisions they made with the Tegra X1 and slightly underclock it for battery life while adding more RAM than the chip normally comes with. If they release the next-gen Switch at any point between 2023 and 2025 that's almost certainly what they'll do. If they wait too long it'll be too close to the release of the PS6 and XB5.
I think they're currently aiming for a March 2024 release, giving the OG Switch a full 7 years before being replaced and also releasing 3.5 years into the PS5's life-cycle like they did with the PS4. Now that the Switch has passed its peak it's time to start seriously preparing for the next generation, but Switch is still selling too well to replace this fiscal year. That may not give Switch enough time to catch up to the DS and PS2, but Nintendo is more interested in profits than sales records.
