Well, as much as the average GAFfer might like a developer putting out this kind of information ahead of release, and being transparent, does it really help them? I think it's approaching the point where resolutiongate is going to hurt the publishers more than MS. Everyone knows about the performance gap, I question there's a significant amount of people who even care, so at this point, it's just PR releasing information that one of their versions of a game is way below par.
Maybe MS's communication advice will be "shut the fuck up", and that's about it. Silent Hills and MGS5 are coming, Nojiri is working on another game that I imagine is using the same engine, and obviously yearly PES. That's a lot of lag that's not beneficial to the sales of those games, the reputation of that engine, or the view of that console.
Only the consumer benefits from the release of this information, and no one cares about the consumer beyond the performance of their own company.
