The Wii U had a lot of those and it still didn't help.

Tue Wii U also had marketing that was so grossly uninformative and so embarrassing in execution it made buying one almost feel embarrassing itself and that was when they could be assed to market the system at all which 80% of the time they didn't.  There's a vast number of factors to consider when examining the Wii U's failure.

Pokemon, Animal Crossing, GTAV, Madden NFL 2019, FIFA 2019, Ridge Racer, Soul Calibur VI, Overwatch, Yokai Watch 4.

hopefully we hear something soon. getting bored of the switch. need new games lol.

THEM 20million switches aren't going to sell by themselves. I still think that Animal Crossing and Pokemon will be this year.

I would like to see some older 3D Mario games to get an HD remaster this holiday.

Because it will be. Also because everyone is begging for a sequel of their big games to be on the Switch. Maybe in 2019 we will see another new IP from Nintendo and hopefully it can have a Splatoon success. 

Difrence is that Wii U started geting good and strong games when alaredy was considered for failure, and later those games couldn't change nothing, while with Switch its opposite situation, Switch is very desired and popular console and with every new good release its becoming more desirable and popular console.

I don't think the Wii U had strong software.

Unlike the Switch, there was no benefit to purchasing the software on Wii U. There was no unique hardware feature that provided a mode to play that would somehow make the Wii U version preferable. There was the unique off-TV play, which was good in theory, but only went so far (about 5 meters). The Switch offers users the ability to pick it up and take it anywhere in the world to play, this creates a unique feature for the software that trumps the higher fidelity or, in some cases, provides a reason to double dip. 

So, in short, while the Wii U did have Mass Effect 3 and a couple of Assassin's Creed games, these would only be strong software if they weren't already available in superior form elsewhere. The only people who benefitted from these releases were those in the market of "I want these games, but refuse to buy games on consoles that aren't Nintendo" which is only a very small number of Nintendo fans. For the majority of Nintendo fans, these releases were utterly pointless.

I wonder if most of those unnanounced titles are third parties.

I don't think SC VI is going to appear on Switch or they would have announced by now.

Overwatch, I have a hunch that neither is coming.

Madden and Fifa depends on EA, so wouldn't bet on those.
