Switch 1 was the work of art. This one looks like the work of A/B testing and “we are losing customers as they choose Steam Deck over us, so let’s make it look like Steam Deck”
Yes this console does feel like a more “grown up” Switch but I don’t think it’s a sign of chasing after Steam Deck; switch has sold 2 orders of magnitude more copies than Valve ever will.
If anything it’s following the same pattern as Wii (white) WiiU (dark) for the successor to be a bit more serious and grown up looking.
Kids who got their Switch 1 when they were 10 are now 17, ready for a more grown up console.
The Wii U also comes in white. My grandparents own one.
Likewise, I wouldn't be surprised if the Switch 2 came in more colors than what's shown, just like the Switch did.
