1. Probably. Even the DS got the DSi, and the 3DS got the New 3DS.
2. March 2021.
3. $349.99. Switch will get cut to $249.99. Switch Lite will get cut to $169.99.
4. The vast majority of games will be 1080p in docked mode, and some games will support 1440p. More games will hit a minimum of 720p in handheld mode. I also think the screen will be slightly bigger and have more resolution. But it will probably be 900p instead of 1080p. There will be more internal flash storage. 64 GB or 128 GB instead of 32 GB.
5. We'll get at least one other Switch SKU at some point, like a home console only Switch.
