Killzone coming to the PSN

[Update] Sony confirmed to Game Informer it will release Killzone on PlayStation Network. The game will cost $9.99 and release on January 24. This is a port of the original PlayStation 2 title.
------------------------------------------
[Original Story] It seems the first Killzone title will soon be making its way to PlayStation 3. The Entertainment Software Ratings Board recently published a rating for the game for PS3, which typically signals its eventual release.

It's unlikely this is a complete "remaster" of the original PlayStation 2 version, but instead simply a digital title of the original available through PlayStation Network. Sony began selling PlayStation 2 titles last October through its "Only on PSN" program.

We reached out to SCEA for additional information and we'll update this post if we hear back.
