I'm probably done with buying game consoles for the forseeable future, considering I got a Switch in '17, Xbox One X in '18 (granted I was able to make back much of my investment by selling back my original XB One model but still). I anticipate milking the Switch and XB One X for at least a few more years, maybe even 5-6.
Next up will probably be an updated gaming PC (mine is from '13 and even for its time was only mid range), but even that will be a couple years down the line.
For the distant future, I'll probably just stay the course with Nintendo + Microsoft, but maybe that rumored Ninty and MS partnership will actually happen by then and I can just commit to one console + ride out a new gaming PC for the next several years.
