The Bernina Record 830 has been around for over 35 years. The 8-Series Bernina 830 was released in 2008 - which Bernina 830 sewing machine are you after?
Why would a company do that? Its not like the old Bernina 830 is an obsolete - machine, well yes, technically it hasn't been made since 1981 - but in reality the machines sell well in the second-hand market and the demand does not seem to be dying.
So my guess is that Bernina is trying to use the enduring popularity of the Bernina 830 Record to launch their top-of-the-line computerised Series 8 Berninas.
