And people who paid nearly 2.5x as much money to upgrade to a III also want to feel they got 'value' for their purchase....
I had an AX8 (twice in fact) and one of the things I did really miss was the bias tremolo. At the same time, when I chose to sell mine, and upgrade to the III, I did so because I wanted certain features. If I could of just sat on my AX8 for another month, got a bias trem, and a harmonic tremolo, for free, I might be a bit salty over why I just dropped $2500, no ? See how folks who paid for a first class airline ticket would react if the airline went and gave away free cocktails to everyone in coach.
Obviously we've got different stakes in the game though... Youv'e got an AX8 and want as much as possible from it, to which I don't blame you, and I bought a III, in part because I felt it was going to provide me with new and advanced features I couldn't otherwise get from my II or AX8.
I don't really care that much either way, and its nothing personal, BUT, at least to some degree, whenever we get a cool new III feature, that no one else gets, it in some ways further validates my decision to buy the III. I already thought it was a good value as is, but with each and every new feature it gets, it makes me like it even more. That is just human nature.
