At the end of the day, people buy the hardware to get to the games. If Nintendo keeps the flow of great games coming, Switch will do fine, if not stellar. It's already at a great starting point, selling numbers comparable to Wii in many places and it didn't have the luxury of being released during the holiday season, not to mention selling at a higher pricepoint than Wii without a pack-in game.
I think games like Mario Kart Deluxe, Skyrim, Mario Odyssey, Splatoon 2, and Xenoblade 2 this year alone along with a peppering of indies throughout will be enough to keep this train rolling for the rest of the year.
