Well it doesn't have any innovation like motion controls on the Wii. The PS3's innovation is in its sheer power. Its got the cell which I guess is good I have no idea what it does. Its got Blu-ray, bluetooth, wifi, USB ports, HDMI, upgradable hard drive (compatible with most laptop hard drives).
I'd say its pretty innovative even if it doesn't have something like motion controls. And there aren't a ton of shooters on PS3 made by Sony. Most shooters are 3rd party. Sony's only ones are Resistance, Killzone, MAG, SOCOM, and Uncharted. Maybe a couple more I forgot.
