The next upgrade will be version 6. Apparently V5 will not be offered as an upgrade - it was shown at Ceedia this year but info is very sketchy on what is new - possibly includes the recently added (to G68) USB input. Looks to only be available from new (like the G68 USB input). We were hoping that JK's Q&A would have shed more light - maybe they do but I missed it.

There are a few recent speculative topics recently on the subject. My guess is we will hear something towards end of Q1.
