I have a couple of essential questions. I appreciate the information might not be available yet, but I can't wait to find out, lol.
1. Has the USB implementation changed ? - The showstopper.
This was a huge flaw on the Pod HD. Big driver issues early on which damaged hearing and headphones as the thing gave out a full volume squeal regardless of settings. Line 6 blamed this on the host environment for a long time. Then it turns out that the USB connector crumbles to pieces if you breathe heavily on it, again Line 6 deny. If the USB hasn't been fixed, I'm not buying one. Fool me once...
2. Can a foot-switch be assigned to an individual parameter ?.
To me this seems like an addition that would add soooo much value that I'm disappointed it never came to POD, especially when DSP time is limited. The flexibility this adds to the floorboard is immense, especially considering the foot-switches can now be momentary.
If the answer to both of these is yes, then take my money ! :)
