I shouldn't worry too much, the last attempt to KO an MP Prime had some very obvious differences,

Last pic on the list. From memory these KOs were made in the same factory as the legit version, but the workers would come back after hours and were using a lower grade plastic with the same mold as the legit version.

Unless the KOers do an exceptional job of counterfeiting MP-10, I doubt they'll get much of the collecting markets money.
