No, no it didn't.

Yes, it did. In the most recent week of data, Wii U outsold PS4 worldwide. Notice the word "technically". Words, you see, have meanings, and if you don't pay attention to those meanings, you'll misinterpret things that people say.

I'll have to say it to you, too, I suppose. Words have meanings. "Fine" doesn't mean "great", it means "fine", "passable", "satisfactory", "sufficiently", "within reason", etc. The phrase "it's selling fine" doesn't mean "it's selling stellarly" or "it's selling exceedingly well", it means "sales are nothing to sneeze at, nowadays". There's no denying that sales in general are depressed relative to this point in the previous generation, in all respects (game sales on current and previous-gen systems, etc). Note that this isn't referring to launch sales, which are always subject to supply, hype, etc. When you factor this in, you see that the Wii U is right where you'd expect, really.

What I find funny is that the same people who shout "denial" at anyone being satisfied with Wii U sales numbers now are the same people (or similar in mentality) to the people who constantly dismissed the Wii's sales numbers as irrelevant, and constantly tried to mark it as "teh cazualz" in order to feel better about their own system - you know, REAL denial behaviour, not just satisfaction with the situation.

Wording of the title make it seem like Sony and Microsoft are bigger than Nintendo in gaming. They're not.

They've certainly had a lot to answer for on that respective front since the N64 though. Keyword there, since, not after.

Not entirely sure what you mean. Who are "they?"  Nintendo?  Sony? Microsoft?  A combination of the three?  Answer to what?  Respective to what?  Being big?  

Nintendo, I would've thought that was self-explanatory. Respective to falling far behind the heights of industry growth mustered by their competitors. 

It isn't self-explanatory when I don't know what the rest of your sentence meant either.  I could only guess that maybe it was Nintendo because you said N64, but I couldn't make out what "answer" was supposed to mean here.  Anyway, on topic, Nintendo is still much bigger than Sony and Microsoft in gaming.  While hardware sales on Nintendo's front have fluctuated, Nintendo is still very powerful on the software front (which is arguably better to have).

Nintendo has always been a big dawg when it comes to gaming. Even though Wii U flopped they still are sellings tons of portable systems. It's Microsoft and Sony who would love to build gaming franchises as popular as Mario and Zelda that are the under dogs in this race. If Nintendo lowers their price another $50 and produces a couple NEW (NOT REMAKES) games with Zelda and Mario their sales will pick up in no time. For the record I own a Wii U but it sits there collecting dust. I like my X1 and PS4 better at the moment.

It's also better to have powerful software relations first and foremost so that the would-be incentive software to buy the system doesn't end up going under the radar, or ends up with Gamecube-like consistency if relations with 2nd and 3rd party partners backfire (Rare and Capcom).
