Breaking news on PGA TOUR 2K21's Twitter feed: Welcome to the new Clubhouse Pass, where you can find tons of new clubs & apparel! Along with that, check out the new holiday clubs/apparel, then take on the newly added Detroit Golf Club, home of the Rocket Mortgage Classic!
I can't wait to strike my first putt with the new flamingo shaped putter! 
The "new content" hasn't been added to the game yet that I can see, but maybe... just maybe they'll sneak a patch into it?
I am all for new "Official" PGA style courses being added to the game. All of the other cosmetic stuff does not interest me, and I would think most of the hardcore players that have been thru all iterations of this game.
But, if there are others out there that are interested in paying more money for cosmetic items, and this keeps the revenue flowing to HB Studios to keep this franchise going I am all for it. I personally won't spend any real money on stuff like that....but from what I have seen in other games, there are plenty who will spend the money.
Back when I played Madden Ultimate Team I was amazed that people spent real money on card packs...like ALOT OF MONEY. I had a 99 overall rated team just by flipping cards in the market, and never spent a nickel of money on card packs. I ended up with every single card/player that I ever wanted just by playing the game.
