Do you remember when Nintendo went out of their way to shout about third party support on the wiiu before it was released?
How did that pan out?
Switch is launching in a time where handheld sales are dwindling, PS4 will be at 52+m, Xbox one at 28+m, and mobile / tablet gamers who may have been tempted in the past are now satisfied with Nintendo progressively giving more attention to the mobile market.
Switch is going to flop, potentially even harder than the WiiU.
It's fine if you disagree, after all opinions are opinions, but all signs point to third party support falling off a cliff within months of release, sales after initial launch spike being sub par and lots of unhappy people due to the budget components used.
Combine that with the market manipulation being carried out by Nintendo currently to remove Nintendo-provided stock of the WiiU from retailers, causing third party stock to increase in price and force potential customers to go with the Switch instead and what you end up with is only the most devout of Nintendo fans marching out on launch week to pick one up, then a veritable retail tumbleweed of a first year.
I also find it laughable that the same sort of people who were falling for old rumours of Nx being more powerful than the Xbox one and PS4 , and relishing the idea of having the fastest console, are now the same sort of people waving the "specs mean nothing only idiots care about specs" stick.
