Apparently at the (right now in session) linux foundation event Register | Linux Foundation Events
They announced that adobe will support OCIO 2.0 at least photoshop and Premiere. (still waiting dor substance…)
Foundry 
Adobe
Maya
Redshift
Vray
Arnold
A bunch more.
Resolve 
Flame
Just alone for keeping in “sync” with maya flame needs ocio pretty please? is there a feature request?
Anyhow: Adobe going ocio is amazing and I wonder how they will fuck it up.
