We'd be having a lot more sources and speculation than something from Denmark, I can tell you that.
Speaking somewhat more seriously, I doubt Nintendo would be saying things like "Switch is in its middle phase" back in November if the successor was out in 12 months - and I know how Nintendo PR speak goes, DS being third pillar, etc. but when combined with the general life cycle of HD consoles and how Nintendo literally can't stock enough Switches to sell, Nintendo just having released the OLED model, nothing outside of some byzantine rumors about supply chain tech really actually signals that Santa is delivering a Switch successor this year. Again, we're talking on the shelves before Black Friday, 10 months from now. You can pull up all kinds of rumors and Bloomberg reports but I simply just don't believe it until I see Nintendo announce it themselves. What company in history has ever released a model revision like the OLED only one year before its bonafide successor?
The only reason to seriously entertain the idea is if Nintendo is abandoning traditional console upgrades and going for more of an Apple-like mode of model upgrades being more blurred and less delineated, but I personally don't believe that is going to be happening.
