Ok, I add my 2 bits. After F1 and V2, chances are further improvements will end, and that is my speculation. We will no longer get better performance if we stand to allow collusion influence competitive behavior. I guess this is China so unlike the US where China protects their citizens employment market with policys like "you must build factories here to gain market access" there is no opportunity loss. Therefore head fi's only concern would be would walnut and zishan v series keep getting better. Back to what matters, Walnut V3 is not released. On a side note, please don't quote me as I want to reserve the right to edit my statements in the event you know happens.
