This argument is a fairly tired one that is pointless, because Nintendo has proved time and time again that they are not a reaction based company. They do not compete with MS or Sony by looking at what they do and copying. They never have. Even with the GC, the power may have been on a similar level, but they still didn't have online functions and it had the mini-discs. They just work within their own bubble. It's simultaneously the best and worst thing about the company, since it can lead both to great success and great failure.
You can argue about it all you want, Nintendo should do blah, or Nintendo could do blah, but it doesn't change the fact that they will always do what they do on their own terms. It's just how it is. No amount of arguments and rhetoric on the internet will ever change that.
For me personally, it doesn't matter where they're at in the "war". I enjoy their games, and as long as they keep delivering them, I'm fine. I don't care what number is where since I'm not a stockholder. As is, I have 8 games for my Wii U, with at least that many more in sight that I plan to buy. It's already paid for itself, as far as I'm concerned.
