Fifa 21 Xbox Series X / S?

Will fifa 21 for the xbox series x / s and ps5 be launched directly on the consoles or will it take a while?

Yes is available directly at launch.

On the Xbox Series S | X you can still test the game with the Xbox Game Pass Ultimate for 10 hours (this is Xbox Exclusive and can't be used on Playstation consoles)

Because I'm unsure because on many sites like giga, gamerpro and various others it says 04.12

04.12 - this is probably an optimized version that will exist in a higher frame rate and a higher resolution.

So on November 10th, I can simply buy it in the microsoft story at the xbox series x fifa?

Yes you can.
