A new Nintendo Switch is on the horizon, albeit another revised version of the console that Nintendo released in 2017. Like last year's revision, the new Switch will feature a newer memory and SoC. These changes have required Nintendo to change the Switch's CPU board too, but the new revision will look visually identical to existing models.

Whoever wrote this has no idea what HAT-002 is, lmao.
HAT-002 is the NintendoSdk EDEV debugger unit, and this change is simply the "Switch V2" version of it.
