Native speaker here.
He pretty much said what he posted a few days ago in Famiboards, that presentations he expected to happen in late September would now be a few weeks earlier than expected. He didn't mention which presentations in the podcast, but did mention in there that we'd have an Indie World in September (which seems to imply that the usual September Direct could happen sooner this year).
(In the podcast) he believes Switch 2 will have a similar schedule (announcement/release) than its predecessor, but that's his own assumption/hopium.
You just got this part mixed up. He just mentions "some things" closer to January, likely aluding to something like a "Switch 2 presentation" and not its launch.
