We're all speculating beyond these known points:
- MR Gold earned through the 'native' MR program becomes MR Platinum;
- MR Gold granted by match from SPG Gold becomes MR Gold.
It has not been clarified definitively whether or not the comp'd UA-affiliated Gold status is considered MR native, although some statements have been made suggesting it is.
Nothing has been said about what will happen for the UA/MR tie-up after this year.
