IK has not moved on from iRig Stomp I/O it is a fantastic controller and interface for AmpliTube (and other similar software). Any problems can be addressed through our support team and they will surely get anybody with issues up and running and enjoying their iRig Stomp I/O.
The pedals are completely different, as is AXE I/O and other guitar products IK has released are also not impacting iRig Stomp I/O. The fact that it wasn't discounted is probably actually a good sign
