FWIW, as early as early September I'd been staying in ex-SPG properties and was thanked for my "Plat Premier" status (this even at a 4PTS). Thing is, about a month later, it stopped, both MR/SPG, and I've been merely greeted as "Plat" since. Don't really care about the "greeting" part, but it's interesting about the changeover part I guess.
