I'd consider that to be reading too much between the lines, or at least quoting out-of-context. He does say "soon" in the same press release, and from playing the XboxOne version this morning, apart from the nice touches like the onscreen control prompts (I could actually play through the first four tutorials without thinking about a manual, and I've never used a gamepad for ED!), it's identical to the PC version. David Braben alludes to that in his press release too, as well as saying that the Xb1 version has helped improve the PC version. Given that the XboxOne is almost just a gaming PC anyway, there's no real reason to think that it's going to eat too much time up, any more than working on the Mac version will.
I think it's dangerous to read too much into pre-prepared press releases anyway. We'll see what's announced for 1.4 soon enough...
