Namco Bandai has now removed the "TBD" release date for PlayStation 3 version of both Eternal Sonata and Beautiful Katamari from the company's official website.
Namco Bandai reps pulled the listings for the non-Microsoft consoles from the website following yesterday’s supposed unveiling of a PS3 and Wii version, leaving only the Xbox 360 release dates as previously noted.
Whether or not the PS3 version listed yesterday was in fact a human error or otherwise it is currently unknown, with Namco Bandai having yet to make an official statement on the matter.
These titles are now 360 exclusives; however, we'll see what happens conveniently at Tokyo Games Show on September 20th, 2007.

None of those titles appeal to me anyways.
even if they don't appeal beautiful katamari is a massive massive massive sucsses in japan an it sells consols so its an obv strat frm microsoft to ship more consols if they have a game the japanese all love
bah these games will come. However, if I lose out on Eternal Sonata I think that White Knight and FFXIII will pull me through =P
I think Katamari is big in Japan when they own the console its coming out on? As its coming out on 360 I really can't see this game being sucessful, I just don't see the Japanese going out to buy a 360 for this one game. As I said the game is big on a system with huge sales but Katamari is no system seller
psn id: gingo... i reckon it was a mistake but only a mistake in that it should not have been announced yet, TGS should be very interesting this year
