Sony has a great brand in PlayStation. Sales of the original PlayStation surpassed 102 million units and the PlayStation 2, which just ended its production run this year, has an installed base of over 150 million consoles. Sony has sold over 77 million PS3s and counting (they'll continue to support PS3 well into the future). The bottom line is everyone knows the PlayStation brand, and that goes a long way in reaching the more mainstream consumer. Sony has also wooed more hardcore gamers with its line-up of exclusive games like Gran Turismo, which has sold over 65 million copies.
