I've put own a wii u and won't buy a switch but that's because I can't imagine buying a Switch for a long time probably 2018/9.
I don't feel upset about the wii u situation and understand Nintendo having to try something new because of the low sales of wii u. I would have been angry if they hadn't released Zelda on wii u though.
I feel like the wii u is a much better product for its day than Switch even though I think wii u was quite poor. Switch as a portable is pretty much only delivering wii u performance and its getting on 5 years since wii u came out and not much better docked. Cartridge sizes are smaller than wii u discs. My wii u has a good range of wii u titles to play most of which are quite cheap plus a huge range of wii titles and if you add homebrew you can add a huge range of other formats including gamecube.
The Switch seems to have limited support even from launch and very little to get excited about. If I didn't have either and had to choose whether to get a wii u or Switch at this point in time I'd happily go with wii u over Switch.
Switch may be a huge success commercially, I don't think so but it may be but it looks to be a complete failure in software terms at least for sometime. It's not just the lack of games but the few that are available are extremely over-priced and not competitive at all.
