Hi,
Reference 8, 8.5, 9, and 9SE are model numbers. The .02 refers to a circuit board revision that happened in 2005 which we made minor changes and to distinct the differences, we name the updated circuit .02. The small increment denotes it being a very minor change.
Ref 8 does not share the bigger chassis as in the current model Ref 8.5, 9, and 9SE, so Ref 8.0 (as well as 8.02) cannot be upgraded to V2 status. In most cases, to original purchaser of Ref 8.0 and 8.0x we provide a generous trade-in value towards the 8.5/9 series.
We have no intention to provide V2 and other future upgrades/updates to the Reference 8.0x series.
Ref 8.0 and 8.02 look like this:

Ref 8.5, 9, and SE look like this:
