Being a PS3 on vitamins (not even steroids) for the price of a PS4. That's a no-no.

You dont even know how powerful the Switch is...

I don't agree on all ports, some games done already what's needed from them, splatoon has already sold enough, they should have created a successor instead of a port, Mario Kart and smash are the same, Xenoblade, tropical freeze may desire ports cos there's more potential in these games than what they achieved on Wii U
Nintendo should realise that Switch system doesn't have enough time on its hands, and they should not repeat the mistake again of releasing a successor without moving their first party teams to work on it, It's important for switch to succeed, but it's also important for it's successor to succeed as well, I say three years of first party on switch and then they should work on the successor
Me I want the third xenoblade, new splatoon, new Mario 3d, & a new Mario maker, just as well as couple of other titles' so no sorry I don't want them to keep porting Wii U games especially those who already done fine enough

Look at it this way, Mario Kart 7 has sold almost 14 million while Mario Kart 8 has sold 8 million and MK7.

Even if we assume that 100% of MK8 owners also have MK7 than thats 6 million MK7 owners who do not have MK8. If that number is closer to 50% than thats 10 million MK7 owners who do not have MK8.

Thats a potential 6-10 million MK7 owners who could upgrade since Switch is not only a Wii U successor but also a 3DS successor.

Same goes for Smash Bros, It has sold 8.35 million on 3DS & about 5 million on Wii U so using the same 50-100% crossover rule, thats 3-6 million Smash 3DS owners who dont have Smash U.

Splatoon has never been on 3DS so who knows how many 3DS owners who upgrade to Switch will get it.

3DS has sold nearly 50 million more than Wii U so there are clearly millions upon millions of people in the Nintendo audience who have not played these games.

Also depending on how much new content they have, there will likely be a good deal of double dippers.

It doesnt matter how many have played it or not. Theres over 6 billion people that hasnt played Mario Kart 8. You make a new console, you make new games for it. Its as simple as that. If you want to remake an old game to make it better by todays standards, then fair enough.

Like I said before, I will be ok with these remasters if they have about as much new content as the games had at launch. So if they are close to twice as big, then fair enough.

A lot of people are missing an important factor for these ports.  Porting these Wii U games helps the Nintendo teams get familiar with the new Switch hardware and gets Wii U game engines running on Switch hardware which will expedite future releases of NEW games on the Switch in the process.  You got to learn to walk before you run.

It has worked for them since the NES, so I dont see how the Switch would be different.

Games were a lot less complex in the past, why would they start from scratch with all the modern work they've done with the Wii U?

Why would they start from scratch? Because they are releasing a new system.

Game engines are also updated and reused on new systems.  And if porting games expedites the learning process of the new system why not use it?
