The Centurian Lounge could end up being a nice benefit. Unless a club is near capacity and they start turning people away...
I have thought of adding the unbranded Platinum card for that and a couple of other benefits, but couldn't make the $550 AF pencil out on top of the Reserve's $450. Unfortunately, I just renewed my Global Entry a year ago. That would have covered the $100 bump in AF all by itself. I would be interested to know how the comp upgrades with no Medallion status will slot into the existing upgrade priority. I am guessing at the bottom? After all of the FOs have received their unicorn upgrades to First class? If that's the case, it's something of a "paper benefit".
Also wondering where they will plan to take something away. Upgrades and Sky Club floor space are limited commodities. Increasing both on this side means that someone is going to lose out somewhere else.
It will be interesting to see how it plays out.
