When the new MSD 6Al2 part# 6421 comes out is MSD going to discontinue the MSD 6al part# 6420?

Nope, the 6420 will still be available. Keep in mind the new 6AL-2 is microprocessor controlled, has rotary dials to set the rpm limits on the built-in 2-step (no more rpm modules) and provides hotter output than a 6-AL.
