Firstly a rumor isn't proof, and it has no place in a rational analysis. When it comes to gaming less then one rumor in two hundred actually bares fruit, and even that is suspect, because the bullshitter hoaxers who perpetrate rumors are often making educated guesses. So it stands to reason that on occasion they will come close, and even then the people doing the judging aren't exactly rigorous in their appraisal. A rumor monger can be all of ten percent right, and some will treat them as if they were completely on target. You should limit rumor speculation to rumor threads.
Secondly you are misappropriating the word hype. It doesn't mean what you obviously think it means. I think you are just using it, because you think it sounds better then someone being somewhere on the range of interested. Like I said it is a exaggerated response, and not a rational response. People can be interested, or looking forward to something without being hyped. The exaggeration is purely emotional, and nobody can stay that high for any extended period of time. That level of anticipation at a maximum can be sustained maybe for a couple weeks, and that is mostly for the very young, or the very bored.

There is actually a severe drawback to holding back too much information. Namely the chance that people may get the wrong impression, and you only ever get one chance to make a good first impression. The absence of information. Could be seen as that absence of quality. Sony doesn't need to empty the cupboard, but they better have the most pertinent details, and announce a solid first year lineup. Otherwise people will default to the more recent expectations. Namely it will be overpriced, feature weak, or suffer from poor software support. We have to remember the media is going to be the go between for most consumers, and will the PS3 launch fiasco, and the failure of the Vita fresh in mind. If Sony doesn't fill in the gaps the media may well do so.
I personally think the worst thing that could happen is that Sony doesn't provide enough information, and the net result is media outlets write stories, and half of their story will be about the console, and the other half will be about Sony's dire financial situation. Which could make a new console look like a mixed blessing. I think Sony needs to own its message. Rather then leave it up to the media to build a mountain out of a molehill.
