They're probably right though

It kinda is an upgrade. That's how new generations work.

Ok, I'm out

N-no! They are liars! *puts fingers in ears and starts singing*

Glad to see Nintendo marketing coming out of the toilet from the Wii U era. 

My local GAME also has an ad. for preordering. Hype!

Hopefully. Nothing comes close in terms of hype. Neither Mario or Splatoon are in the same universe.

Why not? Have Nintendo confirmed it is not coming at launch? What kind of joke is that company that can't have the game ready for launch after all these years in development?

Perhaps, but that remains to be seen and splatoon still hasn't outsold multiple games in the Zelda series. While splatoon performed well on a bad console it also had no competition whatsoever. Your expectations of splatoon might be the overstated importance. But we'll see how splatoon does from here on out.

Don't forget that the high points of Zelda sales wise are pretty high, and BOTW is another title akin to the hype of those high points as well. The lower points of the series sell about on par with Splatoon, main console wise (and sometimes handheld wise). Splatoond numbers are only impressive given the console it's on but again, lack of competition puts that into question.

It doesn't.

Depends on the point of view, but you countering his matter-of-fact with another matter-of-fact gets the debate in that regard nowhere. Here's a mock rebuttal that achieves the same thing yours did:

"it does"

That was the point.
