If it's as much better than Interplay as Sideways is than From Trash, then it will be John's best album yet.
As I regard Interplay as being in the top five of John's career, and Sideways as probably the best Foxx and Gordon album, I reckon you wouldn't be far wrong there Martin.
The parallels between From Trash and Sideways, and Interplay and The Shape Of Things certainly auger well. A good or better release soon followed by a lower profile more uncompromising album, initially only available on the (autumn) tour.
