So he is right? awesome can't wait till I get my ps4, no need to get a pc anymore^^ #freethebieber

This thread isnt about sales. 

Comparing modern game development to game development on the SNES is flawed. For starters, most games on the SNES were written in assembly, which is much closer to the hardware than what is accomplished today. This meant the benefits of reducing x amount of memory usage, and y amount of processing usage could be more easily realized. All you have to do is just write better assembly code that is less wasteful. It is different today in that it is more a matter of technique and/or choice of algorithms that improves the final product. Most improvements occur because there is some type of new programming trick used to achieve the same or a better result, with less power usage. The time and investment into software R&D to find these new techniques has to be quite large for it to happen. That is why only 1st party developers really have the incentive to do it or achieve it. So if there are any advancements, it is less about the console's hardware and more about programming techniques. 

Like I said...

I was disputing the first clause, "The more time you spend developing on a console the more you understand about it" it is not understanding the hardware that makes games look better on the same platform today, everything is too high level for that. It is developing new software techniques in general. These techniques can be used on any hardware. 

Are you trying to suggest that the PS4 is more powerful than the PC? Because ALL of those games could run on PC. And look better, in-fact, one day they will, thanks to Emulation. All your games are belong to us.

You should try playing a high-end PC game in Eyefinity/Surround Vision or on a 5k resolution monitor some time, you might just start eating a hat if you think a console could hold a candle to a PC.

None of the consoles this gen were powerful enough. Nintendo decided to be crazy and release a last gen console, and Sony and MS both decided to save themselves some money by selling at a profit right from the beginning of the generation (which isn't how consoles were done in previous generations). Quite a few developers have commented on how the specs this gen were lower than they expected, alot of those early gen games that got downgraded were due to the developers expecting more power. 

As for UC4, it is a beautiful game, but let's face it, it's pushing PS4 very close to it's limit. We may see a few games that rival UC4 graphics on PS4, and maybe some developer (likely Naugghty Dog themselves) will top it, but any graphical improvements over UC4 later this gen will be negligible. There's a reason why Sony is releasing PS4K Neo, it's because PS4 is nearly at it's limit already only 3 years into the generation. That is the price you pay for designing a console with basically off-the-shelf components as opposed to a more expensive custom solution.

There's a crucial difference, PS3 used a custom solution. Because developers start off not knowing much about a system's architecture when a custom solution is used, throughout the generation they constantly find more power "hidden away" that they didn't know they had to work with. PS4/XB1 basically use off the shelf PC components, any developer that has been developing games for awhile was familiar with that hardware already because they've likely released a game on PC at some point (especially 3rd party developers).

In other words, because developers started off with more familiarity with PS4/XB1 hardware than a typical console that uses a custom solution, they started off the gen getting more out of the hardware percentage wise than they would have if PS4/XB1 had used more expensive custom solutions. It's quite possible that developers have already managed to access 80-90% of what PS4 and XB1 are cable of. It's why we're getting a hardware refresh after only 3 years for Sony (PS4K Neo), and I suspect MS will also either refresh XB1 soon(XB1.5) or release their next console as early as next year (Holiday 2017).
