No... and if we've learned anything from the pre-release chatter of the 500x don't believe anything until you see it or hear it from line6 directly.
its a reasonable assumption that it will get the same processor upgrade as the 500x... and obviously the footswitch upgrade doesn't apply...
i wouldn't expect much beyond that.
the POD HD Pro prices went down and some shops do already list a POD HD Pro X and told that it may be available mid october.
Are there any Infos available about that unit (Improvements / changes compared to the non-x model; maybe some specs)?
