KB + Mouse are for desks. Consoles are for lounges + TVs. TBH actually the Xbox 360 would be better with KB + mouse support than the PS3 as it has a better scaler chip which supports monitor resolutions.

What does scalable monitor resolutions have to do with KB and mouse support?

KB + mouse lives on a desk. Monitors live on desks too.
