I'm guessing that the big Taiwanese/Chinese places forging dropouts by the million must not be making horizontal dropouts anymore.
Bianchi makes the Milano, San Jose, and Pista with hoizonal drops. They just need to look in their own parts department. Shimano is offering the chain tensioner option so gearhubs can easily be retro fitted to existing derailleur/vertical drop frames. But putting it on a new production frame was cheap and ugly.
