Not sure...I like Sony exclusives, but I like what MS is pushing as well right now. Need to see more on PS5 before making a decision. There is also a distinct possibility that this is the gen I choose PC as my secondary gaming playform as well, so there is that.
In any case, Switch will likely remain my main platform due to portability. I will definitely have SOMETHING to pick up the few games outside of the Switch library that I feel I must play however.
