the game freezes because it's not compatible with the ps3 yet. it requires a firmware update to play and no updates have fixed it yet. it will work eventually. just keep checking after each firmware update.
great news!!! the latest firmware update will allow you to play ultimate ninja 4! finally! woot! just thought i'd give a heads up to everyone still waiting for it to work. i've been playing since last night and haven't had a problem yet.
You must be mistaken, there's nothing about that listed on the website. *I looked at the link you provided and I see that Clash of Ninja Revolution 3 is coming out in November for the Wii. *That is not the same game as UN5. *There has been no UN5 announcement.
Release dates for games on GameSpot are often times submitted by users, and sometimes the the gamespot staff approve release dates without double checking. *You need to look for news articles - not a little one liner like that.
