If any status matching were to occur (and that's a big if as I haven't seen any mention of it in the announcements made so far), it would be when/after the actual integration between Hyatt and MMS takes place. The date for that is currently unknown. More likely IMO is that Globalists don't get matched to MMS Goldsmith, but rather they get perks at MMS hotels similar/comparable to perks at regular Hyatt hotels.
