My guess would be we see further differentiation of the Platinum vs Platinum plus $75K spend levels.

Probably similar restrictions on Centurion Lounge access will be made to what was previously done for Delta SkyClub. Might even combine the two into one bucket that could be used at either lounge. Restrictions eliminated once $75k spend is hit.

They could also introduce the long rumored enhanced CC with a higher AF, but it seems they are focused more on encouraging people to spend rather than encouraging more sock drawer customers.
