Ill get this movie, but many of this "genre" are so low budget, I dont think the studios would even waste the time to do it....
Boyz N the Hood (John Singleton)
Blood In Blood Out aka Bound by Honor
Clockers (Spike Lee) (maybe part of a SL collection)
Are the 3 most likely to get the treatment if any of them do.....
Even though I did enjoy Fresh, I dont think it has the "power" that the others do...Menace II Society is just too low budget
...
The funny thing is Ive seen all the ones you listed plus some, really though, until there is more of a hold on the market I dont think youll see movies like these in anytime soon.
I think its great though that they are trying to diversify the content on Blu-ray. I think this is something that is important to do, so that there is a broader audience buying movies and players....
