Just got the email posted in Loyalty Lobby a little while ago:

CHOOSE THE WAY YOU'LL EARN
Get ready, Duke787: On September 1, you can register for our next promotion and choose how you'll earn (up to 50,000 points!) Your bonus. Your choice.

Won't hold my breath after the terrible summer promo. Already have Platinum in the bag for next year (and with the 15 CC nights am already at Gold for 2018 too) so unless it's a strong offer I'll be looking more towards Hilton (if they continue 2x) and Hyatt (lots of conferences in Vegas coming up all at M Life hotels) for the rest of the year since I have a chance to retain Diamond with at least one of the two and the bonus at Hilton is substantially better.
