No. They're companies. They market a product, make money and keep thousands of people employed.
Are consumers guilty of once again keeping unrealistic expectations and spending money unnecessarily? I can only say I'm as surprised by this generation so far as I am impressed, which is very little. Probably because most of 2015-2016 felt absolutely no different.
If you truly believed you'd be buying a console that would play massive open-world next-gen titles at 4k60fps without setbacks, you were simply dreaming. It's only natural to expect these companies to try and sell you on these lofty visions, but if you want to know what you're buying you should wait to actually see the product in reality before paying up and complaing you've been given a rough deal.
That being said, I don't think there's much wrong with either system as is. They both do the job for a modern console, as far as performance goes at least. Series S maybe a bit more disappointing, but I haven't followed it much.
