Spotted at Trek World, displayed at the factory during their demo rides, a lugged steel retro concept bike:

Sorry, no closeups of the lugs, but they were fairly decorative, definitely more ornate than traditional Trek lugs of the past. Literature said they were laser-cut. Love the retro logo, and headbadge.
Dear Trek: yes, please for production...
