Switch is a niche product that targets niche market. It's trying to replace smartphones & tables in mobile gaming market, and consoles in households & living rooms.
If it doesn't come out with many great exclusive games (that will WOWWww gamers) in 1 year after its release date, then it's DOA. They did an awesome thing with Gamecube, and that is bringing RE:Remake & RE:0 which i love to death. But did it work? No, it didn't. And now they only bring a remastered downgraded Skyrim. What a joke. Gamecube was DOA because Gamecube had nothing in its weaponry. Switch on the other hand only has joycons to overcome all its weaknesses (weak cpu & gpu).
I say that the Switch is DOA, but we can only know for sure after 6 months after release(1 year at most). The Ps4 & X1 killed Wii U 1 year after release, Wii U could still breath fresh air for 1 year without competition. Switch will fight Ps4, X1, smartphones, & tablets in the market. Logically, Switch is DOA.
