Let me take a stab in the dark: the firmware will be released this thursday around 7pm EDT.
I think threads like this are truly unnecessary. You guys already know that the whole FAS + Beta team is putting maximum effort into the Axe FX II, thus it's logical that they'll release the firmware as soon as humanly possible.
That's all that matters, and no begging and whining will speed up the release process. So why not chill out, read a book, watch some movies, play some games, play some guitars on 5.07 (because it still sounds good even though 6.0 is right around the corner), listen to some music, paint a picture, shoot some photographs, calculate something interesting, think about god and the stars etc. etc. there are so many interesting things to do instead of just wasting time waiting on 6.0.
And to address ETA shortly: While I do sometimes wish that there'd be ETAs just for the sake of better organization (e.g. not bothering to fine tune presets when you know that a major firmware will be released the following day), I also see the downsides to this concept, namely the additional pressure on the whole FAS team.
Cliff has been working his a** off consecutively for the last 8 years or so... no need to make matters even more difficult by adding "estimated" deadlines.
