1) Yes, considering... But that's a very one-sided way to view the Wii U. You must also consider the fact that:
a) The video game market is shrinking. With the imergence of Smart Phones and Tablets into today's market, most of the casuals have jumped ship. You also have to factor in the exclusive nature of the market. Most 3rd parties are only aiming for men between the ages of 25 and 40. They aren't trying to attract the younger crowd or even women. Because of that, fewer and fewer people are interested.
b) Software sales are down - especially for the PS4. Even though the PS4 is selling a lot of hardware, it's hardly selling much software. This is very frightening, because it means consumers aren't buying PS4s to play games on it. So, what exactly are they buying it for? This is hard to pinpoint exactly.
c) The Xbone is doing much worse right out of the gate. Even with that said, the 3DS's sales have already peaked. This is a sign that video games are becoming less and less important. 

If you consider all of the above, then you can see why the Wii U isn't doing as well as the GC was during the same period when the video game market had been experiencing growth.

2) Nintendo is a family company. They aim for everyone (including females). Would you have thought the original DS was designed to attract females? Of course not, but yet it did. Even the Gameboy SP attracted more females than any other console during its time. Do you think Nintendo somehow designed the system to attract females? Of course not. It was the games that attracted females. The same applies to the Wii U. The system isn't what would attract females, but rather, the games.

1) Mario Kart 8 has been in the Top 10 worldwide for 2 months now. That's _worldwide_ mind you - meaning MK8 has been in the top 10 in every region for 2 months. No one is saying Mario Kart 8 is all Nintendo needs from here on out. However, to pretend Mario Kart 8 isn't doing anything for the Wii U, let alone Nintendo themselves, is very short sighted. You also claim the Wii U is selling poorly. I'd say, in this present time, the Wii U is finally selling at acceptable numbers. So, it's no longer selling poorly. It's selling better than the Xbone.

2) You're very confused. The PS2 hype didn't kill the Dreamcast at all. The Dreamcast was still a commercial success. Sega simply went out of business. The Jaguar is a failed console. The Virtual Boy is a failed console. The 3D0 is a failed console. The Dreamcast is NOT a failed console. 

3) The point of the link was to show you that Nintendo's female-centric strategy is already active. Will Animal Crossing come to the Wii U? Of course it will. Will other female-centric games from Nintendo hit the Wii U? Eventually. To assume Nintendo isn't going target the female market is just silly - especially after Nintendo has already shown their plans to do so.

4) The only FPS I've seen that pushed consoles was Halo. A large library of FPS could potentionally push consoles, but outside of Halo, this is certainly not the case.

5) Goldeneye and Perfect Dark were the only FPS from Nintendo. Turok was from Acclaim and the rest are old PC ports. The Xbox and the X360 had way more FPS than what the N64 had. 

A lot of what you're saying is based on wild assumptions and misinformed opinions. You should honestly research some of the stuff you're saying so you can get an idea of whats really going on.

But the market is shrinking. Don't you even care to research this stuff?
