What about the new gimmick? I'm sorta expecting something like this
You know, I really think that the Gimmick thing is overrated. I think Nintendo will market "a new way to play" because they always have, but there is as much iteration as experimentation in Nintendo's history.
The SNES and the GameCube were power driven updates. The N64's weird controller is really a product of 3D, which is a gimmick, but also, is just More Power. The Wii was wild, but the Wii U wasn't a radical new concept. Both the Wii and the the Switch made motion
controllers as fundamental to the machines as trigger buttons, even as motion
controls fell off.
The Wii U's gamepad allowed all new async gameplay concepts with a single machine, but for the majority of games it was really the handheld version of the DS, with an always available inventory touch screen. The Switch doesn't have that particular feature, but the whole Switch concept takes the most successful "new way to play" from the Wii U era (offscreen play) and built a whole ding-dang console out of it.
The Virtual Boy was a failure - decades too early - GameBoy Color and GameBoy Advance were really just more powerful game boys. The DS was insane, obviously, but the 3DS, as wild as stereoscopic 3D was, it also really just made 3D platforming possible on that tiny screen and was effectively totally optional.
Of the 13 consoles Nintendo has made, only five have been centered on something other than new visual capability. Two of those were massive failures in the market (virtual boy and Wii U), and one of them, the Switch, could be argued as secretly a giant visual leap for their handheld line that supplanted their TV line.
Switch was marketed with magic joycons that could make you count ice cubes through haptics. There will be
something fun in there, and it will likely be overhyped at launch to give folks something to talk about.
It seems like if they could get streaming to the dock, it would kinda be over. Dual screens and async play represent the only major features of their other consoles not replicated on Switch. DS games could comfortably come to NSO, as well as a couple lost Wii U games, but also, I think the inventory on second screen concept is a genuinely great reason to play games on Switch instead of other consoles, even if you're not a handheld player. It's one of those rare perfect ideas that just needs to be salvaged.
