Comments such as these lead to the logical conclusion that the unveiling was obviously premature. Which isn't at all surprising since Sony didn't showcase a working model at their event. I know what I am about to say is going to most likely be outright ignored, but I am going to say it anyway. Sony not having a finalized design at this point in time should be genuinely distressing to the fans. Sony is basically trying to throw a console together overnight, and that has never been a formula for quality workmanship.
That is actually a formula for disaster, because it could, and probably will result in Sony truncating the testing phase for their hardware. It is not as if we as gamers haven't seen the consequences of this first hand. This is a leading contender to explain why early 360s had a massive tendency to go Chernobyl. This kind of time table isn't going to allow Sony the time it needs to run anything close to a real world stress test on their hardware, and maybe barely enough time to bug test the installed software.
Lastly these comments aren't ambiguous in the least. Though I can see why some of you might try to argue that they are. He is talking about known specs being subject to change, because there would be no point to inform the public. About changes to things that they didn't know about in the first place. It actually makes a great deal of sense when you take into consideration Sony's financial situation, and the global economic situation.
Sony just doesn't have the cash reserves, or the credit worthiness to run the risk of over estimating a uncertain future marketplace. You can credit them for wanting to push the envelope with their technology, but that doesn't mean that they can, or even should throw all caution to the wind. If the global economy sees a sharp downturn they obviously want to have the option to pare back their hardware. To keep it affordable not just for consumers, but for them as well.
I for one wouldn't be shocked in the least if they had to scuttle a couple cores in their final design. It would simply be a matter of the most expedient solution. Cutting back on the power wouldn't require them to radically redesign the hardware, and wouldn't require them to change their business plan. It wouldn't even be instantly apparent in the final product. Just in the graphics of games a few years down the line. Once developers start to get the most out of the hardware.
It might be a problem then, but with good fortune it could be a problem in a drastically improved economy for a company that might have better financial prospects at that time. Now I am going to say something that is probably also going to get ignored. Sony obviously doesn't have a strategy of its own, and thus isn't in control of its own destiny in this industry. That is why they are still dithering on their specifications, and that was why their event was a straight up strategic failure.
If Sony intended to strike first then a strategy of rapid dominance was called for rather then what amounted to a reconnaissance in force. The net result of which makes them look timid and uncertain. Comments like this add to that impression. Effectively they are saying that they might change their minds. Now they don't even get the best of what they could have gotten, and have given a edge to their competitors. If not the initiative.
