I got a Switch when it first came out and there isn't a single big feature I can think of that would get me to buy a new Switch version that Nintendo could implement without pissing off the original adopters. However, with the right combination of, actually possible, smaller features, I may be enticed to get a new Switch. If the new Switch had a better battery, blue tooth, better kickstand, higher quality dock, and improved joycons, then I may seriously think of upgrading. None of those features would make me feel I am playing a lesser quality version of a game on my old switch, but with all those features together it would be a big enough quality of life improvement to possibly justify a new purchase.
