Steamdeck isn’t in competition with Switch 2. Totally different markets.

One is a full on powerful PC shaped like a portable gaming tablet, and specializes in gaming. With a pricepoint to match.

The other is a dedicated gaming machine, using cheaper parts, with every aspect specifically thought out for one, and only one, purpose. With a price far far FAR cheaper. Switch 2 hasn’t been price named yet, but I’d be shocked if it was over $350.
