In 1999, WotC put out a 25th anniversary celebration set, which was the Holmes Basic set, with a bunch of other goodies in it. It was in limited editions and by all accounts sold out, was quite popular, and now demands pretty hilariously high collector's prices (partly because the L3 module included isn't available in any other place).
I fail to see why WotC couldn't do something similar again.
