Following the revelation that Killzone 2 became the fastest SCEA title on PS3 to reach 500K sold, Sony today revealed that the critically acclaimed first-person shooter from Guerilla Games has sold over one million copies worldwide. The company pointed to the game as another example of an "only on PlayStation experience," and noted that it will "continue to drive incentive for hardware sales throughout the year."

SCEA boasted that "approximately 1 in every 3 PS3 titles achieve Metacritic scores of 80 or higher, which affirms PlayStation's proven track record in delivering rich and relevant entertainment content."

Although Sony is confident in its PS3 lineup for 2009, the company also continues to support the PS2. Today, the company stated that since the PS2 price drop, it's seen "positive internal sales momentum" for the nine-year-old console.
