I bet there's more than a chance that Jonsered never will...that is the Jonsered folks back in Sweden.
I asked an old Jonsered dealer about that once, when I was buying my 670, years ago...he could order and get a "west coast" saw, but it amounted to a large aftermarket filter, and a hole in the top cover to suit. Just wasn't worth the extra money he'd have to have, against a saw off the store shelf. He believed that the optoin was at the behest of N. American distributors, not intended by Jonsered.
I've also heard here and out in the real world that Elux is bound by contract to continue to supply N. American distributors with product, and that kinda bugs Elux...they'd rather have undiluted access to the market with a single product line.
So, Elux is probably not in any hurry to offer the goodies to extend a basic saw into broader markets. If N. American dealers aren't able to compete, well, it's not like Elux is gonna worry too much.
