My experience is that the Axiom staff are pretty candid with the community here. I'll bet if there was a major initiative afoot, we would probably know about it.
AND even it we did not, your M80's or M60's would always sound just as sweet as they do now. That's the beauty of any kind of technology; it's not that the thing you bought becomes degraded or obsolete, it's that your expectations change. The product you bought continues to perform at a level consistent with your expectations at the time you bought it.
I KNOW that my M60's will continue to be fine and satisfying speakers regardless of what kind of marketing and development takes place subsequently. Don't cheat yourself out of some immediate pleasure; there will ALWAYS be something "better" on the horizon. Enjoy the moment!
