Al's latest column seemed to imply a limited number of the Musical History box sets being released...

don't worry about trying to get one of the scarce "gold vinyl" editions, since the replacement black vinyl edition now available on line and in the parks may probably end up even rarer (since I think they will most likely top out at 2,500 units total over the the 5,000 original gold that were issued)
Is this true? Should I buy the set soon? Or will they be available, at least for the 18 months of the HCOE?

Thanks...
