Did I say they won't do it? I said they gave it a low priority. The question is how long it takes to deliver a promise or at least provide specific dates.
No, you didn't say those words, but I think people misunderstood the "vagueness" of what you did say.There is probably no reason for iBasso to do it.
But I agree that it is not high priority to them. As a matter of fact they even said so on here.
Having said all of that, IMO it IS in their best interest to get the DX300 up to speed with the DX320 for software. This might save them the hassle of programming twice when they release a new amp module, since they fit both devices. But that is all conjecture on my part.
