Wii U Regrets:
I went to reserve the Switch the morning after the conference! I feel this is what the Wii U should have been. I remember laughably, taking the Wii U tablet out of my gaming room and into the bathroom to do the remote play option (yes Wii U let you play on the tablet away from the TV). The second I got not even 6 feet from the console, my wireless connection on the tablet went out! This feature was laughably bad and now the Switch is doing it perfectly. They had the idea with Wii U, but the tech wasn't there yet, I guess.
I would completely regret buying the Wii U if it wasn't for Smash Bros and the hours upon hours I spent over the years, with that one game. It's sad though because the only other Wii U games I have are Mario Kart and Wind Waker HD.
Zelda Delay and the New Rumble Tech:
Also, I mainly bought a WIi U for Zelda Breath of the Wild. Sadly, that was a mistake. Now it would be illogical to buy it on a soon to be dead system. Aside from that I'm very interested in the Rumble HD technology. Being able to feel objects inside your hand inside the controller and the weight of something growing, really intrigues me!
So, besides Zelda and Mario Odyssey (which looks really unique) there is Xenoblade Chronicles 2, and Dragon Quest 11. Already that would be more games I will own, compared to the entire life span of the Wii U!
No Need for Another Handheld:
As far as Nintendo making another handheld, I feel that would only be detrimental to the idea and spirit of the Switch. We have two in one now, there is no need. And now we will have two-fold the games! Not every game has to be a monster house of graphics. We can have the lower end and the higher end of these games, at the same time!
And eventually a few years down the line I know almost for a fact, Nintendo will release the Nintendo Switch Pro. Or something along those lines with improved battery power. It's inevitable!
