I don't think there's a release date. I don't think we know if this is a retail game or a PSN download. I know we don't know if Katamari Forever on PS3 supports the screenshot feature (PLEASE PLEASE). At this point, all we know is a vague impressions article on Kotaku when the game wasn't even hands-on. Oh, and there are Trophies, but as it is past January 2009 we shouldn't even be bringing that up anymore.
The menu screens - I'm guessing these are menu screens - look to have a pop-up book feel that I already adore.

Especially since that amusement park screen brings us this lovely horror:

THE KING OF ALL COASTER!
The Kotaku comment thread brings us this curious query that I can't decide if it is sarcastic or stupid.

I guess I have to go with stupid since Kotaku Law states that all sarcastic comments, when challenged on authenticity, must be followed up with "I WAS BEING SARCASTIC, DURRRR."
Anyway, here's a few more screens of something I will purchase regardless of reviews.



BEAR COW!


Freakin' Bear Cow...
Those last three screens prove it'll largely be built from the levels of previous Katamari games. I recognize all of them.
Yep, I'm buying it too. I still have We Love Katamari and want to play it with my kids, but a native PS3 version would be very nice.
Also, freakin' paper cranes...
