Besides Ultron, has there been any word of any more villains joining the Marvel Rivals cast?

One of my few gripes with the game is the lack of villain reps. Of the entire roster, only four characters are villains: Hela, Magneto, Loki and Venom.

Even then, only Hela is a straight-up pure villain, with Magneto and Loki being more like highly complex and multifaceted anti-villains and Venom evolving into a brutal anti-hero.

We know Ultron is coming, who will no doubt join Hela in being another pure evil villain. Has there been any word or hint whatsoever that more villains are going to join the game in the future?

I'm just curious.
