Someone on the PlayStation Brazil (opens in new tab) social media team got a bit overexcited this week and hit 'Tweet' before thinking, telling everyone that Overwatch 2 (opens in new tab) would be hitting PS4 in 2020. Blizzard's yet to announce a release date for any platforms and hasn't commented on the tweet, which has since been deleted.
Voxel (opens in new tab) spotted PlayStation Brazil's blunder before it was deleted and grabbed a screencap for posterity. As well as claiming that it would be out in 2020, the the tweet linked to an article (opens in new tab) with "hot information" that never actually surfaces. It's from November and doesn't mention a release date.
While Overwatch 2 was playable at BlizzCon, Jeff Kaplan said it was still in early development and that Blizzard didn't have a date in mind. Slow and steady seemed to be the message. It's unlikely, then, that it would launch so soon. Best take this leak with a big pinch of salt.
