I have actually put my Axe in mothballs pending new Axe Edit and FW. I'm still on 7 and have been waiting all these months for AE to upgrade. For me, the reasons are 3-fold:
1.) I use Axe Edit heavily to do everything. Could I use front panel? Yes, but don't have the time to deal with it. AE was one of the primary reasons I bought the Axe because it made my workflow easy.
2.) I do not want to invest hours and hours tweaking presets in 7, 8, 9 only to have to do it all again (with scenes which I am super-excited for!) with whatever FW we have soon
3.) I have never been an "Axe only" guy. I have a lot of nice amps and still believe that they are, generally, better than the Axe's renditions of them (although I must admit missing the EFX and ease with which they are used in AE). I love my amps. But, I love my Axe too for the amazing flexibilty it gives me w/o lugging 500# of amps/ cabs/ EFX around.
So, I'm on "Axe Sabbatical", back to using my amps. When AE comes out and we have new FW to match, I'll spend the hours to do what the Axe does best and I'll be super happy. But, I'm super happy now too :razz. I don't see any sense in spending time doing a ton of work on 7.0. However, I am not upset at all with Fractal and happy to wait for all the exciting new changes we are about to see.
