No decision yet but it will be reasonable.
We are offering $500 ($550 for Ref 8b) credit for Ref 8 owners to trade-in to Ref 8.5V2 so your purcahse price is $1250-550 = $700.
Therefore the V2 upgrade for Ref 8/8b will have to be lower than the trade-in offer.
Ref 8.5 (100W, V1) -> Ref 8.5V2 (200W, V2) upgrade cost $400 / unit so Ref 8/8b upgrade will likely cost the same. Well, here you go, I just worked out the price

We are very scientific and structured so everything just fit into place.
