I already have and played MCC on Xbox, so the answer is no to a day 1 buy on the Switch 2. I'd pick it up on a deep sale though, just for the novelty of it.
I played them all on release and then played the H2 and H3 online until it dried out. This is for people who want to experience the games for the first time, or people who want to have them portable.
Considering how long it took to get the MCC working properly on Xbox, what are the chances of a prospective Switch 2 port not being riddled with issues?
