Tonearms longer than 12 inches


I'm curious to hear anyone's speculations on the
future of tonearm developement. What could be improved ?
As well, what lengths could we reasonably expect to see
in a pivoting arm ? 14 inch ? 16 inch ?

stringreen---I've heard that about the Helius arms of old. They are kind of the Jaguar of arms! Hopefully Helius has improved, as has Jaguar, the build quality and reliability of their current arms.

"The way Jaguar got better is that they sold the company.   ...Tata"

After Ford put $12 billion into acquiring, modernizing, and improving Jaguar, Ford sold it to Tata in a fire sale when in financial straits circa 2007.  Nothing like audio.
