I can confirm Smash Bros Switch and a few other games from this list are coming within the first year through multiple trusted sources I happen to got myself, one of these sources is said to have contact relations with Nintendo of America. The source has been verified, though I'm not allowed to reveal the source's identity. It seems that the source is reliable and somewhat believable, due to the fact the source is said to have contact relations with NoA and is verified.
One source has told me specifically that Smash Switch, the new Nintendo IP, the new Retro Studios game, and Dragon Quest XI are "launch window" games, not launch day titles, so a month or two after the Switch launches. I can also confirm through the source that the first six games shown on this list are launch day titles. No word if DQ X is launch day or not.
The same source has told me that Smash Switch is specifically a port of Wii U, with all Wii U/3DS content, and a bunch of new content and DLC being added. Finally I can confirm through the source that this new launch window game from Retro Studios is a new "Wave Race" title for the Switch, and that new IP is being described as "fun and insane, unlike anything Nintendo has ever made".
Please note that this leak isn't officially confirmed by Nintendo.
EDIT: This is a repost, due to the fact I got some more info (as seen in this repost) from the same sources.
