While I still think the best time to release Switch's successor is alongside Zelda in 4 months, I do think your read is spot on, we don't know how much info if any is in this article, and it is suggesting a product that would release this year... If the info is real, we still don't have a real timeframe as it's too vague, are deals just now starting or are they closing and components will be shipped for production next month?
I tend to line up multiple separate sources when available, and that would suggest that this information is older, if there is any here to begin with... but I'm also bias towards a launch in May with Zelda because that was the original plan I heard years ago, that the game and system were tied together, but the pandemic and Zelda's delay have put the relationship of these two products into question, there is always the option of releasing the hardware at the end of 2023 with Zelda DLC that also adds RTX features to the game.
I'm firmly waiting until Feb 10th has passed before I move on from a Zelda launch, but yes this article if it has real info, suggests a 2023 launch, that isn't what is being discussed privately, and projected publically, but from the info I've been able to gather, the source for a no 2023 hardware launch is not reliable, from what I have heard, people who know the source of the info is dismissing it, and people who are hearing it second hand are more inclined to believe it... I think with what we know about where the hardware and development software was at last year, we should be looking at a release sometime in 2023, so it comes down to some other reason for a 2024 launch if it is the case, because the hardware and software for the device should be ready for retail sometime this year.
