And in my first reply to you I pointed out that this game is also coming to the Wii U - and that there isn't much else to play for quite some time after the Zelda launch. Zelda DOES count, but it's still a soft launch of the console with few games and missing features. I said that ONE game doesn't make this a great OR a good launch; it IS a soft OR weak launch. Maybe, at best, it's an ok launch, but that might be stretching it.
You really don't get it, huh?
Zelda stands so tall that in the real world people won't even consider which other games and how many the system will launch with. The decision to buy Switch will have already been made before that point. This is what a killer app is.

Switch does not match the definition at all. Switch also does not have a weak launch, because it's getting out of the gates with a killer app that is followed up by a massive multiplayer hit in the following month. It doesn't matter that Zelda is also on the Wii U, because the two versions launch day and date, the Switch version is superior and nobody is going to buy a Wii U at this point. It doesn't matter that Mario Kart 8 was on the Wii U, because the Switch game is a complete package of the biggest Mario Kart game to date and all the sales data we have access to shows that remasters of blockbuster hits are comfortably among the topsellers for a new system. That's two killer apps in the first two months that hit different spots: One is a huge singleplayer game, the other one is a multiplayer champion.
