Geoff Goodman spoke about potential hero reworks coming with Overwatch 2 during the Reddit AMA of July 2020. These reworks may or may not be confirmed at BlizzcOnline in a few weeks.
To remind you of what could be happening:
Roadhog
May be moved to the Damage role.
They told us his playtested damage kit in the 1-3-2 experiment in this post. To summarise, 400 max health, take a breather no longer reduces damage, scrap gun gets buffed. Jeff does say that this was not planned for 2-2-2 though, so take it with a grain of salt.
Note: In the public 1-3-2 experiment, he was not playtested as a Damage hero.
Roadhog Quote
Mei
May move to the Tank role.
Geoff Goodman says they could “maybe try” Mei as a tank, and she “comes up quite a bit [when speaking about reworks]”. He mentions her secondary fire does too much damage and has too much range for a tank though.
Brigitte
May move to the Tank role.
Geoff didn’t speak much about this. All he said was that Tankgitte comes up “consistently” (see above Mei quote, where he also mentions Brigitte).
Symmetra
May move to the Support role.
Geoff speaks about Symmetra several times in the Reddit AMA. Firstly, he says:
“[Healing Turrets] ended up just feeling like a mismatch, but honestly i’d be up for taking another crack at it at some point.”
He suggests that turrets were her primary/only way to heal, and says perhaps the Healer Sym experiment “could have gone better” if she had a different, primary way to heal with turrets just being auxillery healing.
In another answer, he says “the door isn’t fully closed yet. its possible we’ll re-try her as a Support (healer) in the future.”
His final mention of a Healer Symmetra is when he responds to a question asking “Do you regret any hero reworks?” to which he says:
“Maybe we could have pushed harder on Sym as a healer. Maybe we can still revisit her as a healer.”
Symmetra Quotes
Shortly after OW2 was announced, Jeff Kaplan said at an Overwatch 2 panel:
"Today on November 1st 2019, I do not think any hero needs a major rework. Major reworks are messy and scary and not one of the best things for us to do. They can occasionally be exciting and occasionally they’re neccesary…But we don’t have any major reworks planned.
Now there is some time before Overwatch 2 comes out and I think a major release like Overwatch 2 is a great opportunity for us to revisit everything and to really reconsider everything so I would not rule that possibility out."
Note: This was said 8 months before the Reddit AMA. It’s quite possible that Jeff’s stance has changed on this, especially considering Geoff Goodman (lead hero designer and head of reworks) has shown a degree of interest in reworking several heroes.

Please bear in mind that this is purely speculation based on some vague developer quotes. Manage expectations! Geoff only showed interest in reworks, he did not confirm they were reworking any heroes.
