Looks like these are finally coming out. @Scott W. I know you are on the hunt for these as well. According to Cigar Coop, shipping to retailers this month:

Cigar News: Fuente Fuente Opus X 20 Years Celebration Commemorates Two Decades of OpusX

Just an FYI, if any of you all see them, PM me! I'll gladly pay you for a box, assuming they aren't being marked up like crazy!
