Switch/PC combo. Any other console is unlikely but not impossible.
And since I'm playing on a laptop right now (needed to be very mobile, but that will end this year), my next-gen system will be a gaming PC. Zen2/Ryzen3, Navi, 16-32GB RAM (depending on the price, can always upgrade that one later on), 512-1GB M.2 SSD (again, depending on price by then - though probably 1GB considering how far they're dropping) and 4-6TB HDD. And a Blu-Ray drive for my movie collection and retrogaming (I got tons of PC games on discs).
