I think it depends more on the federal government officially deferring to state drug laws (unlikely) or taking action to de-schedule marijuana specifically (slightly less unlikely).
Right now the only people who can grow cannabis openly and "legally" with any degree of safety are the states themselves, which kind of puts a damper on market competition.
