You guys are looking for conspiracy when there seems to be none.
I don't think you're familiar with the context of the discussion to which you've interjected. Nobody is saying that Sony is wrong to push its own platforms during events such as PSX, just that there has been a demonstrable difference in openness between PSX 2015 and 16, which is most definitely the case. Is that important, given that inconsistencies can be immediately clarified? I suppose that's a matter of perspective. Should a lack of clarity be expected? Generally, yes, but last year Sony made a point to accurately represent the nature of the games it featured, only to walk back from that this year and either obfuscate or outright misrepresent the truth. In fewer words, the point isn't that Sony is wrong to push its own platforms, just that the switching of gears is disappointing as Sony made a point to set an honest precedent only to do a 180 due to a perceived inconvenience.
