As an owner I am biased but I do think Litespeeds and Lynskeys will be collectible and some of their bikes will be classics. Without implying any sort of xenophobia there will always be collectors of American marques. The Paramount collectors of today will beget the Litespeed collectors of the future.
I've been around long enough to where I still feel that a "thin" tube lugged frame looks "right" but my TiG welded 853 LeMond and my Ti Litespeed with brifters that have worked for thousands of miles, sitting on wheels that re seriously light but also bulletproof are hard to beat.
Really the only drawback to modern stuff in regards to function is that 10 speed chains don't last very long.
