This was actually from June 5th, but I didn't see it posted anywhere. Per this article from Dualshockers as well as the original tweet (with a link to the website).
The game was originally announced as a 2020 release for PS4/Xbox One/PC.
Are we thinking a delay?

Bandai Namco announced a new Tales of Festival stream will be held on June 14, and it'll include the "latest information on the Tales of Series, celebrating its 25th anniversary in 2020″, but it was also made clear that "There will be no announcements and game news", meaning no Tales of Arise news.
Instead, this stream is an appetizer for Tales of Festival 2020, which was delayed from 2020 to March 6, March 7, 2021, because of the Covid-19 pandemic. The theme of the stream is to enjoy Tales of Festival from home (with the hashtag #おうちでテイフェス), and will be including the having fun together part of Tales of Festival, not the new announcements part.
