I like FPS and RTS on my PC because of the higher RAM and powerful video card. Higher RAM is something that the console should have by now since RAM price is so cheap and games developer really needs them.
If console like PS3 or Xbox 360 has 4GB of RAM, think of the possibilities the system will be able to do. Now if the Xbox 720 or PS4 have at least 16GB of RAM, I could see millions of enemies attacking just poor old you. Wouldn't that be something.
