I think the PS3 enables sony to compete in multiple markets , as it compliments other products it's Sony's portfolio.
Blu-Ray
HD-Content
HD TV's
But then I'd still argue that they are in competition with Microsoft's XBOX 360 but they have less to loose from selling less hardware than Microsoft because of the other benefits Sony experience from their console.
I don't really see the Wii and the PS3/360 as direct competitors , they compete to some extent but It only looks like the Wii is dominating both because the XBOX 360 is doing better this gen than it did last , I think people would be more ready to acknowlede this if the 360 flopped.
