How much percent of something produced can it actually be before you have to do some internal justification on the term "Limited Edition"..
if its 500 LE GB pins
and 1000 Premium
and 2000 Pro's
then that is 14.285% so you are at about 15% for a Limited Edition.
of course anything sold beyond those over the next couple of years would push it toward the %10 Limited edition level.
If you never reveal how many are sold you never have to say what "limited" means.. Yes they of course only make so many and then stop but overall I think there is a consensus on what range Limited is from 10% to even 25% but if 40% or half were limited edition of total produced then it losses its value from a marketing and product standpoint. IMO of course.
