Fils-Aime says around two million Switches are being prepped for the first few weeks, which should be enough to cover demand, especially as we're not in a time of "peak seasonality" (which we're presuming is the run-up to Christmas).
Some of the concern from gamers has been prompted by the NES Classic launch, where demand has far exceeded supply. According to Fils-Aime, Nintendo was surprised by the popularity of the retro gaming box, but that won't be the case with the Switch.
The Nintendo boss also revealed more details about the Switch's online service, confirming that the one free game a month will only be free for that month. He also said there's more information on the way about backwards compatibility with Wii U games.
With just weeks to go, there are still questions to be answered about the Nintendo Switch, but we're slowly getting the full picture of the 2017 and what it can do. Most recently, Nintendo confirmed that the Switch won't support the StreetPass feature and the Miiverse social network.
