I mean, I don't think it is a clear cut case of "it takes time."
We don't know what it takes.
Support for platforms grow in ways specific to that platform. There isn't some "it took PS4 this long to get X, so Switch will get X in ~that time too. Wait." Moreover, development is simply not in the same place at different far-flung launches and nor is the the lay of the land wrt all the various hardware.
In some sense, yes, wait and see what the whole picture will be but we should keep an eye on what support Switch is getting and where other support streams it could get are going and if they do start including Switch or not. Which, maybe they will in time but support doesn't come purely as a function of time and never has.
