Hello there Nintendo Switch fans!
We've got only 10 more days until E3 2021, what I've known about this console is going to be another iteration of the Nintendo Switch but being a high-end model and capable to run on 4K resolution, either on TVs or monitors.
By June 4th, 2021 this will be revealed.
