Lifetime points/nights/status has been displaying in a flaky fashion as of late.
As much as I would love to have absolute confidence in Marriott, I'm not going to wait for August 1st and assume everything will go smoothly. I will be saving my Lifetime Plat qualification and plastic membership card, and I'm going to ask Marriott to confirm my lifetime nights/points totals in writing so I have documentation if August 1st comes and all of the sudden my status isn't what it's supposed to be.
