Switch 2 is an iterative version of the Switch. Everything I wanted in it - backwards compatibility, better specs, not OLED so one can be released later, better joysticks, etc. all seem to be happening. I don't have sales projections, but I think it's a safe bet it won't flop like the Wii-U,etc.
Add in continued transition to digital sales, the growing player base, continued monetization of IP (movies, parks, Pokemon even), I think it's a low, low risk situation with good reward.
EDIT: Also Yen is cheap.
