This is a repeat of what the demise of Sony's Vita meant for Nintendo. Back in the day (2017) a lot of people were oblivious to what kind of developer shift that would lead to. There were questions about how many games Switch would get, but it was actually a sure thing that Switch would get a lot of games. Many third parties simply had no choice but to support Nintendo if they wanted to keep their business as good as it used to be.
Now the demise of Xbox will do the same. The writing was on the wall since one to two years ago. AAA productions required three platforms (PC, PS, Xbox) to mitigate the risk of the high development and marketing costs, so now that one of these three is going away, it only makes sense to replace it with something else. And the need to replace Xbox also means that Switch 2 is taken much more seriously than Switch 1 was. It isn't only about technological specifications, it's also about the will to do it. Switch 1 was an afterthought, but Switch 2 is baked into the development roadmap, so competent ports/multiplat versions will become the norm rather than the exception.
Legend11 correctly predicted that GTA IV will outsell Super Smash Bros. Brawl. I was wrong.
