We confirm that sale for Game Pass Black Myth???

I am going to wait, Season passes seem to go on sale quite fast for example The Black Ops Pass for Black Ops 3 was on sale over Christmas and only a small amount of DLC has been released

I picked up the black ops pass for black ops 4 it was on a great sale and i am thinking about getting the black ops II pass also.

Postponed to November 28, will be part of Black Friday sale at $19 game + $6.50 season pass

there are always sales in way of the weekly game sales in the store and deals with gold, however we have just had the summer sale, so I reckon the next big sale will be the Black Friday sale. But keep up with the latest news as there are always game related
sales from specific publishers throughout the year

Games go on and off sale all the time, frequently with no advance notice. Sales start normally on Tuesdays at or around noon UTC and go until the following Monday. Major sales are once a quarter or so (except for Black Friday and Countdown, which are in
November and December, respectively), and the next one should be the Spring Sale, which hopefully will begin in the next week or so.

To come back to the Game Pass statement: yes, Forza Horizon 4 is on Game Pass now, but sometimes players decide to discontinue access to Game Pass. Knowing that, you can still purchase the game, even if it's on Game Pass. What makes this even better is a 20%
discount on all games that are currently on Game Pass, so if someone had GP and wanted to buy the game, it's 20% off regardless of a current sale.

(Of course, if a sale is running, the 20% discount most likely won't apply; that is, you can't stack discounts.)
