Been thinking more about this after some comments that have been popping up online in various forums.
With MV recently saying that there will no longer be LLL boxsets unless a unique opportunity presents itself. I have a feeling that if the TMNT John Du Prez Scores get a release it may just be a 2CD set, or a 3CD set akin to the Ira Newborn Naked Gun Trilogy.
I'm still hoping this shows up for Black Friday, if not a 2017 release to coincide with the 30th Anniversary of the Animated series, and my mind would be truly blown if the animated scores made their debut.
