Who would be working on them? I thought they moved the studio to other things then closed em
Vicarious Visions doesn't exist anymore and got absorbed into Blizzard as Blizzard Albany so they're probably not a dev
Beenox was the best guess I saw of maybe who was doing it. They've managed to survive all this time, and they have a long, long history of working on the Tony Hawk franchise. (Among the studio's first game jobs was handing the Mac/PC ports of THPS3, which led to many others in the series. They also did work on ports of THPS1×2 Remastered. ) There's no insider rumor of this being true, but it would make sense.
Toys for Bob could be doing it, but they've been working heavily in the CoD mines and also launched that Crash Bandicoot GAAS so I don't see how they would have the time.
Vicarious Visions is now part of Blizzard (sadly, imo), so they're likely out.
The other guess I'd throw in is Velan, the studio formed by Vicarious expats. (They did Knockout City and that Mario Kart toy game. )
