The Wii U is, for me, the best console I've owned so far. I know some will compare the specs to the PS4 (or even the PS3) or XBoxes, etc..
Here's the thing: I had a PSX, PS2, PS3, and a long list of other consoles. The Wii U is one of those machines that I go back to again and again to play. For the PS-line a lot of it was, "Wow.. Look at those graphics!!," and after an initial playing period it'd sit dormant. The Wii had the same problem (except for the wow-graphics bit). It was OK but I thought that the GameCube was SO much better in terms of game play. I'd go back to that again and again when I had it (gave it away to my daughter who still has it and still plays it).
The Wii U was a flop, though. A horrible, horrible flop.
Some thoughts on this: There was a rumor that Nintendo pulled back all of the remaining stock of Wii Us. I have a Target across the street and haven't seen a Wii U there in months (August, maybe) until after the 1st of the year and then one, I think bundled with Mario Kart 8, showed up. I'm pretty sure it's there right now.. at $300. WTF?? How is it that 4 years into the failed system's life the console is selling at $300. How is it that it's not marked on clearance for $150? Nope.. Sits there collecting dust at $300.
Meanwhile, Nintendo's new system is going to be priced at $300.
There seems to be a huge disconnect here.
Some other thoughts:
Ethernet: Nintendo has never made a console with an ethernet port. The Wii and even Wii U should have really had one built in. I know both have WiFi built in but WiFi isn't very good with long term changes (DS and 802.11b / WEP being a good example). I can still plug in 10Mbps ethernet devices into a switch and they'll still work. I can't with old WiFi devices or, I have to go through a lot of work and kind of open up an insecure hole in my network which I don't want to do (and that doesn't always work). Still, for the GameCube, Wii, and Wii U you could buy an ethernet port which was nice. I prefer to have everything that is sitting still in my place hard wired.
Switch being a portable home console: It's neat but I don't know that I care. I don't know that, realistically, I'd take my switch on the go with me and that leaves me thinking that there are limitations to it being made portable that really didn't have to be there.
Memory: 32GB was small was the Wii U was released. Thankfully you could plug a hard drive into the back and, for me, that's one of the best things about the Wii U: All of my games are in the box. I don't have to have shelving/space to take up a bunch of boxes for games that really just gather dust. I kind of get that they couldn't have put a hard drive in it for power (see the above paragraph about how the probably not-much-used portability will create other limitations) but they could could have made the built-in memory something like 128GB or 256GB. I think if they had it at 128GB that people would still be complaining that it was kind of small.
Games: I think that it's pretty obvious that they missed the mark here. People are excited about Zelda and some about Mario (didn't do anything for me - I really think that Super Mario World 3D hit it out of the park for just shear fun) but, that's basically it. Yeah, there are some other odd ducks in there but you get 2 games about 8 months apart in the first year. Smells of Wii U success all over again.
Reaction to press conference:
I saw some of the YouTube videos of people at the event and it really felt like they were trying to find something to get excited about and, at the same time, feign excitement for what they were being shown. It really felt like a lot of "big smiles" for "this is it???"
Online reviews haven't been kind, either. A lot of it has been what we all saw and what's been rehashed here.
One more thought on the price: I think $300 would have felt better had the Wii U been priced at $200ish for the last year and maybe $150 on clearance. I think that the remaining high price of the Wii U makes the Switch price feel odd like Nintendo doesn't get it.
I don't see me getting a Switch. There just doesn't seem to be anything there for me.
My only caution to writing it off completely would be to look back and see how they pulled the 3DS out of the pit of despair. It was fully tanking in that first 12-18 months and they took it from there to being a great little portable gaming system.
