At over 3.5 million units sold in just four days, the Nintendo Switch 2 is now the fastest-selling game console of all time, and shows no signs of stopping, with some retailers still having trouble keeping them in stock.

Some 3.5 million units sold in four days is fantastic but doesn’t override the “Mario Kart World” price or ROG Xbox Ally gamble.

The first Switch was such a hit that Nintendo decided not to mess with a good thing. Instead of releasing a successor that feels like a generational leap or a pivot in a new direction, it’s following up the hugely successful original with the Switch 2 — a welcome upgrade that largely sticks to the formula.
