The PS4 is one of the most balanced console I´ve ever seen. It reaches 1080p with good quality textures. The CPU is just enough for the GPU it carries, the memory is 8 GB, but only 5 can be used for games, as 3 are for the OS. Just enough for today games. The GPU is good enough for 1080p but not more than that. The blue ray carries 50 GB, just enough for actual games. If you consider placing a better component, then it wouldnt make much sense, since the others wouldnt keep up. If you place a worse one then it wont be able to handle today games at 1080p as it does. So it seems the thing is just perfect balanced for what it designed for. Also its balanced on everything else. The SO is well balanced between speed, games and media. Sony asked the developers what they wanted, so it has a very good third party support. Also Indy support too. The price is right too. Everything is balanced and the sales are reflecting that.
