While all indicates that Nintendo isn't fully prepared for the Switch launch, it's not a soft launch, but rather a full scale console launch (albeit an imperfect and probably improvised launch), with all the marketing behind it. I just cannot understand the disasturous PR - for some aspects, like online, they should've prepare all the necessary information or should've ommited some vague presentation parts alltogether.
People who don't consider one of the most known and beloved IP's in the history of gaming a system seller are delusional, but success of Switch launch is directly tied to BotW. If it indeed turns out to be Nintendo's Skyrim, they will just need to sit back and watch people fight over every Switch unit on the shelves for months to come. In hindsight, not lowering the price of Wii U was a great move for Nintendo, since there is almost no incentive getting a Wii U over Switch to play BotW.
