Resolution races on consoles are dumb. It takes something like 2x the CPU power, 2x the RAM, and 4x the GPU to truly go from 1080p to 4K without upscaling and provide a full 4K experience. And with all this extra power, it still doesn't take into account the extra power needed to create better base graphics or more sophisticated gameplay. Resolution races have happened at least once before on the iPad. The iPad has a handful of games that run at 2k+ resolution. But the sophistication of all of them in terms of gameplay and polygon count, is from the PS2 era.
