According to the blowout post, MC and MK would still remain. I'm not a big fan of this change, and don't think it really saves that much time.
My best guess is that this is a Nat Turner-ism where he and his buddies decided to get rid of it, since the market largely ignores cards with qualifiers; at one point, they were trading around 3 grades lower than the same grade.

If they were consistent with their grading standards and gave all Mint conditioned cards with 90/10 centering on front a PSA 3 with no qualifiers, then I'll be interested in seeing how those cards are treated on the secondary market. Because the assumption on the buyer's part is that they're damaged (surface wrinkles), and the centering is incidental. However, if they got a 9(OC) they would be worth a 7 on the registry and a 6 or so in sales price.
