I mean, the Switch has sold over 146 million units by now. Sales numbers for the Steam Deck aren’t public, but I’d estimate them around 3 or 4 million at most. That is a big difference.
For comparison, the PSP sold 80 million. Even the PS Vita sold 15 or 16 million. The biggest seller among handhelds is still the NDS at 154 million.
Of course, these handhelds have been in stores for a lot longer than the Steam Deck, but those numbers are a lot bigger!
Switch sold almost fifty times more in its lifetime. Do you expect the Steam Deck 2 to teach those sales numbers? I mean, it would be a miracle for Valve.
