IGN has updated their list containing US, UK, JP, and AU release dates for PS3 titles. However, be aware as they state:
Note that these are tentative release dates and are subject to change. Since release dates change on an almost daily basis, be sure to call your local retailer to make sure the game you're looking for is available (TBA indicates that no release date has been determined yet).
The entire list is available from the link above, or http://ps3.ign.com/index/release.html.
