So, my last post was about the possible Xbox 720, and the fact that gamers want better graphics, but compared to PCs, the consoles can't live up to demand.
This is becuase gaming PCs are constantly updating, but consoles aren't, so game developers are restricted by the older hardware. See the picture below:
As you can see, the PC has better colour depth, better shadows, textures and better overall detail. This is why recent games such as Crysis 2 can be played at full graphics on computers, but, the console version is played at lower graphics.
This is why the consoles need updated, and we could see the new Xbox being announced at E3 (see my last post.)
