As others have suggested my money is on an M6 or M7 re-fresh. Cost wise I think it'll be within +/- $500 of the current offerings.
I bought a new M-A from Tamarkin last year and would be happy to shoot it for the rest of my life. Only thing that'd make me reconsider would be an M-A with a rangefinder that magically never goes out of alignment... and that's not going to happen.
