The key part (which is why this is here I'm guessing) is that they basically confirmed GTA 6 is already in active development - scroll to the last section near the bottom titled "What's Next".

We'll see if it's more of a GTA 6 or more of an excuse for GTA Online 2.

My verdict's still out on whether GTA 6 or Metroid Prime 4 will release first.

For those not aware: Metroid Prime 4 was announced in 2017. Development was apparently so bad that the all the work was scrapped and restarted with a new studio in 2019. (With an uncharacteristically candid announcement/apology from Nintendo). And very little, if anything has been heard since. https://en.wikipedia.org/wiki/Metroid_Prime_4
