Dragon's Dogma 2 is CPU capped, and I'd imagine GTAVI will be as well.
But yeah, there's not a whole of of things pushing AI or physics or whatever else you'd use a CPU for. Though more should appear as time goes on.
The Slim is on sale for $399 with a copy of Spiderman 2 at the moment. $100 more than the slim makes sense. That being said slowing sales of the best selling console already shows how much Sony and MS need to switch to mobile consoles.
But! Next Xbox, if it launches in 2026, could be a 20CU 6tf machine for $399, then one with a $599 60Cu/24tf chip and a vastly more capable cooling system for when you plug it in. This gives customers of the bigger one a fast stationary machine and a mobile one at the same time.
