As I said, 2 years ago, you know when they still had the lead and yes I would require Nintendo to put in some sort of "effort". It's the totally opposite of what they did for the 3DS. When the 3DS was failing, they went for an price cut and boom--sale spike.
Can't be done, please. Games can be patched easy enough, most games wouldn't even need to.
Nixing the gamepad first and foremost throws all DS Virtual Console under the bus. Miiverse would be severely hampered by the lack of being able to draw or quickly keypad in posts at all... and then there's games that do use the gamepad in a very significant way, such as the art academy stuff, Kirby and the Rainbow Curse, Nintendoland, ZombiU (which Ubisoft sure as well aren't gonna put the time and money into patching), Splatoon (again, that's a game that loses a BIG part of it's gameplay with losing all the super jump and gyro aiming, which is REALLY good, by the way. the local multiplayer in that game is garbage because of the lack of gyro due to fairness.), and Super Mario maker would need heavy overhauls and would not be as fun as a result. some stuff like the Smash bros. stage editor and a few other things would just have to be gated off alltogether.
So, we're on a multitude of effort here and just ripping out a ton of infistructure... but you know what comes at even MORE of a cost? the lost of the Gamepad's NFC reader. now we're talking about either having to bundle an NFC reader in with the console, or losing what HAS been working for them sales wise, which is Amiibo. there's at least 3 or 4 games out there entirely anchored on Amiibo (Mario Party 10, which would also lose the Bowser Party mode that even makes the game woth a damn without a gamepad, Animal Crossing Amiibo Party, Let's Tap! Amiibo...).
this isn't even mentioning tossing out the window things like the quick-boot, the gamepad's ability to give you notifications on events, and just... so many little UI fixes that would have to go into the sort of massive overhaul in order to not split the userbase... and for what?
an underpowered Nintendo-box? The indie stuff is nice, but there's no longer off-TV play to promote you from getting it on a Nintendo console Vs. Steam or another console. It's still saddled with being shackled to all the Wii infastructure, needing the technology therein to pair with Wii remotes Via Bluetooth and have a have pointers. That, by the way, is the only way to play certain games STILL is with leftover bits and bobs from your Wii. Do they drop that too? do they alienate even more of the fanbase and put out a cheapy, chinsey product that is such a barren desert of a library that we're now competing with the Ouya? Wii U pro controllers aren't much differetn from the Ouya controller at this point, and poeple buy those things to shove Munpen64 onto and then have more N64 game access on it then the Wii U currently offers with their N64 virtual console offerings.
I admire the sheer balls on Nintendo for not bieng wishy-washy on the Gamepad. maybe the idea was half-baked ands they turned out to not have as great of ideas with it as one would hope... Unlike the Kinect, the gamepad isn't actively hurting the experiences that it's involved with. I can't point to a game and go "this game sucks and it's the fault of the technology inside the gamepad" like I can with something like say... The Fighter Within.
