Superman took over a month to sell out. Everyone always says a week or two but it didn't go WL till after a month of being upWell let's see, Batman and Superman sold out of 2000 and 2500 EX's in 4 days and think it was 16 days respectively(Someone can correct the superman one) Wonder Woman has 3500 EX's and has been on sale for 5 months and counting and was just shown to probably be Statue of SDCC this year.
It could of course be fake but if it was real, would I be surprised? No, not really.
