As much as I want more updates for my Mark device; I can understand not wanting to do this for more reason than just the upfront time cost. If you have ever maintained code that was never intended to be moded like this and that was back filled to implement a moded version via many single line ifdefs, etc, it is not only painful to do upfront but it can also dramatically increase the chances of introducing bugs, create mode specific bugs, or cause support/debug issues down the line. I can't imagine how deeply the AX8 forked the firmware code base combined with the existing Mk1,2,XL,XL+ diffs.
FWIW, whenever the final update comes for the Marks and later the XL series, I am confident Cliff and CO will have done all they can to make there customers happy.
Now that I have had time to mull over the situation, even though I could afford to flip from II->XL. I think whenever updates for my unit stop, I am going to not flip it and wait for new hardware. I did not switch from Ultra to II until the II FW was in double digits (and I still have (and love) the Ultra
). I think I am going to go a similar route here... Refine the heck out of my tones/rig and not worry about FW churn until a really new compelling HW unit is available; has been on the market a little bit and is at mid-life.
Plus, even if I flip a unit my wife always registers it in her head as 'another expensive new music thing'. Which would make the III upgrade something that'll require a bunch of explaining.
Maybe I'll start putting a $20 bill under the mattress once a week until then; then I could keep the Mark and have three generations of Fractals whenever a new big H/W rev hits.
