Saw that before, and I think the answers is yes, they messed up. Looking at the Cuaba pics you can see the bottom of the box under the single cigars. Hard to tell on the Montes. Guess you never know until they are actually released though.
Yeah, effups like that are not uncommon at Habanos website. For instance they list wrong size for some vitolas (e.g. Robusto). In fact now the site it's much better than before; still requires lots of fixing.
Cuban cigar website gives the correct box counts: Cuaba Piramides -10, Monte Sublimes -10, PSD5 -25.
