If PSA were to become a monopoly what would happen to the market regarding SGC cards?

[bbeck]

Although I own both PSA and SGC cards, I have a much larger % of PSA. Hypothetically, if PSA were to become a true monopoly in the grading business, what would happen to the market of SGC cards? Obviously, no SGC guarantees would matter anymore and crossovers and breakouts are always a crapshoot. What type of toll would it take on the SGC graded inventory and price levels that exists today? Would it increase the % of raw collectors? The key to the question is not to give a biased answer because you despise PSA, but an objective answer of what might really happen and how, in your opinion, the majority of collectors would react (not just the pure collectors).
