At this point, my opinion on Saviors is more or less the same as my opinion on RevRad. A good album but too derivative of what they've done before. It has stronger production & lyricism (at least for the more political tracks) than RevRad but I think RevRad probably has the better songwriting overall and isn't as derivative.
I'd say it'll still probably be a couple years before we hear anything about the next album. We might get a couple standalone songs in the meantime like Pollyanna but idk.
I hope the next album isn't anything like the Deluxe tracks of Saviors which I felt were particularly weak compared to the standard album tracks.
I dislike FOAM but I do hope that the band steps out of their comfort zone a little bit more for the next album. They don't need to change producers, I think we'd all be happy to have Rob stay but they need to change things up a bit.
