May is absolutely not "early" 2023. June is also 100% completely and utterly summer- it's meteorological summer's first month. It's also the month of the Summer Solstice. Come now, are you really saying the Summer Solstice takes place in "sort of spring"? That's absurd, even by astronomical seasons' standards where it (quite bizarrely in my view) marks the first day. The first day of summer is certainly more summer than "sorta not really".
May is also summer... where I live. And where Microsoft's European headquarters are. It's simple. May, June and July have the most hours of sun; and thus, are summer. Autumn, the leaves begin to fall, the days get shorter, it's definitively Autumn. Halloween is a festival to mark the beginning of Winter, so, yep, November's winter's first month here! In fact our word for November and Halloween are the same; and we don't even have a word for October, just a noun phrase meaning "End of Autumn".
There are quite literally dozens of calendar systems. Some places have less than four, some countries officially recognise astronomical summer, some, meteorological summer, some others, such as mine, their own system from thousands of years ago that we still use today because it works. Which is why I avoid speaking about these things in terms of seasons; it's incredibly unhelpful.
Now, you know what there AREN'T dozens of? Sources claiming the new Nintendo Switch is slated for a mid to late 2023 launch. May is not early in the year, no matter how you slice it. April I would expect to be the absolute latest, if someone told me "early next year" and they meant "May" I'd tell them off for being a liar. March is more realistic, even then.
Late 2022 early 2023 as far as I've heard, as far as Nintendo's concerned, means 2022Q3 or 2022Q4 (Nintendo's '22Q4 is January-March). A launch aiming for one quarter and hitting the next isn't a big deal. But aiming for one, missing two, and falling into the NEXT FISCAL YEAR is practically preposterous.
