Of course not. They've re-released most good Wii U games on Switch anyway. And nobody wants to play Wii games anymore.
(Except for Galaxy 2. Why do you hate that game, Nintendo?!)
I replay wii games all the time. They may have re-released wii-u games but htere is a ton of great wii games still stuck there:
1. Mario Galaxy 2
2. Zelda Twighlight princess
3. Muramasa The Demon Blade
4. Little Kings Story
5. Punch out!!
6. Trauma Center Under the knife
7. Wii sports and resort (switch sports is crap compared to them)
8. Fire Emblem Raidant Dawn
9. Red Steel 2
10. Dead Space Extraction
11. Last Story
12. Monster Hunter tri
All great games on wii that aren't on switch. Yeah some don't like 480p but they look fine on a 1080p tv as long as you have an hd adapter or component hookup.
That being said, nintendo would never do that.
I am still concerned that the cartridge games will come over, as they will probably only do digital bc and people who have been buying carts will have a bunch of useless plastic for the next switch. Hope I am wrong and they use the same cart format.
