I have an original Axe II that I bought really soon after it's release. I had an Ultra several years before that, various Line 6 before that. Although thanks to Suhr Reactive Load, I've been back into loving amps more the last 3 months than ever, I couldn't see ever going without the Axe. I firmware update periodically but haven't given any thought to it going EOL. I wouldn't be angry if it did. Although not exactly the same, I look at it in the same context of something like Mesa going Mark IV to Mark V.
So I agree it's been a helluva run. And I didn't even mention all the flexibility it has in combining with the Suhr Reactive Load and my amp? Simply Amazing.
