Bill,
I would say that the first gears will be available early part of next year (but that is dependent on Bjorn pulling his finger out and he is renowned for not doing this in a timely fashion ), and as I said, they can be retro-fitted. Anyone who purchased one of these boxes now would get the new first gear at cost when it became available.

The step off to convert to a shorter ratio would be like doing a standard gearbox....
