I talked to one of the Spektrum Reps at the Toledo show a couple weeks ago and he confirmed that the iX20 is coming but that there had been a few minor issues and could not tell me when this new TX would be available. He did say that he had personally tried it out and it had a faster processor and was much quicker when making changes. He did not have a price but speculated that is would probably be a little more than the DX20 had been selling for in the past.
