GeraltOfRivia_PL: Do you agree with me?
No I don't, and it is pretty clear from all you say, that you don't have much understanding of technology ... hardware and software. Don't be fooled by all the specs and numbers ... there is a lot more to it than that.
For starters, there is optimization. With true optimization you need far less computing power. PC's are not that optimized, so generally brute force things, whereas Consoles will be optimized.
Then there is the development cycle. That means you cannot change the specs that developers are building to too often ... they require stability and known factors. This why you rarely have issues with a Console, compared to the many issues experienced with PCs.
It is also all about cost and hardware production and development, where all the bits and pieces are ordered and bought in bulk, and they would want to recover their outlay.
etc etc
Not to forget the development cycle of the console itself, which no doubt doesn't really start until prior one is released, and at that point there is no games yet to test it with, so they need to go into development too, which cannot happen until the game developers have something to test with. And because they are usually wanting to incorporate some relatively new technology, it all takes time to understand, develop and test.
