No, Nintendo always likes to cut corners with otherwise straight hardware, and it may seem like potential on paper but it'll likely end up like the Switch 1 were you are limited to what you can do with it docked and then undocked will decline by default.
I don't see Nintendo putting in the expense to be notably better than the Steam Deck which would head toward the GPD/Aya territory when Nintendo wants to sell at a profit and has no interest in taking any loss. I don't think they will go higher than $299 again, at most they may do $399 if they are not able to drop the price of the current Switches but I think they will go for a $100 discount on current Switch and Oled and do $299 for the Switch 2 imo.
