I'm still thinking it will be holiday season this year, or shortly after in 2020. While it is true that Nintendo has said the Switch successor is not the focus, unprompted, what that did is begin the discussion about the Switch successor; and "we have nothing to say on the matter of X" has always been videogame publisher code for "Stay tuned for details on X" - especially when the President of the company brings it up unprompted. Nintendo was also saying NX wasn't the focus in the months before the reveal trailer, Nvidea was saying that they had no projects relating to Nintendo between the Eurogamer leak and the Nintendo reveal.
I can't see why Nintendo would create a scalable hybrid console and forgo one of the strongest benefits and opportunities of the architecture; iterative hardware upgrades. Especially given some of Switch's first party software would greatly benefit from running on higher clocked hardware. Additionally, Switch software is developed with scalable performance in mind; and as software on mobile phones and PC, usually, it is only an optimization patch that is necessary to take advantage of the upgrades.
I describe myself as a little dose of toxic masculinity.
