Depends how you define v2. If you define it as a revision to the original version then -
The DSi was an upgrade to the DS but not a whole new console generation.
The Wii Mini was a downgrade (seriously) to the Wii to make it cheaper/smaller.
The New 3DS was an upgrade to the 3DS similar to the DS->DSi upgrade.
Plus all of the Gameboy and Gameboy Advance models which you could argue were often more revisions with some new features but still compatible than a totally new product.
Such as the Gameboy SP and then Micro which were totally new designs for the Gameboy Advance with a better screen but otherwise the same console.
okay, I never went to the nintendo portables, so I was shockingly oblivious about these. I define v2 as both "set of games you can play on it is identical to the first one", and "not a retro notalgia remake". But even by that standard, wikipedia tells me you gave a lot of good examples. I can only hope the switch makes the list, because I'm not interested in spending significant game time with a handheld tablet, but I also need enough distance to flirt with their limitations.
They don't revise their home consoles much, but they do revise their handhelds. So... probably. This console seems so flawed and badly designed it kinda needs one, quickly.
Some of these revisions even had their own sub-revisions or regional variants like the Gameboy Lite. The Gameboy Color is the only one I can think of they didn't revise significantly, but you could argue that the Color itself was a huge revision of the Gameboy Pocket with a Colour screen.
Well if you count the Switch as a portable, they've done at least one revision/refresh of almost every generation: Game Boy Pocket, Game Boy Light, GBA SP, Game Boy Micro, DS Lite, DSi, 3DS XL, 2DS, new 3DS. They've actually really gone to town on revisions lately with handhelds.
TV consoles are a different story. The NES and SNES had later variants, and there's the afterthought Wii Mini, and that's all I can think of.
They've done at least one revision of most of them, usually with significant cosmetic differences and less features. There was the top loading NES, the SNES Mini, the GameCube was revised and the digital output port was removed, and for the Wii there was the version with the GameCube ports removed and the Wii Mini with all the remaining ports removed.
GBA has three generations (stock, SP and micro), 3DS had 2 or 3, depending on if you count the XL. Wii had two (original and mini). Other then the New 3DS, none of these have been system hardware, but given that the Switch is built on a tegra chip, I can see it getting upgraded with full backwards compatibility at some point.
Hell I don't even count the GBA Micro, considering it couldn't run GB games despite having a Z80, simply because they dropped 5-volt support. That's not a refresh, that's just taking a dremel to the thing!
