No it won't, but I'd love to live in your dreamworld.
Again, Level 5/MS relationship is crap, secondly, the PS3 version (being a different beast than the DS release) is exclusive.
Thirdly, NB has no say in this, though if they did the 360 versions of games getting an enhanced port for PS3 makes more sense with Eternal Sonata and Tales of Vesperia (at least this one in Japan)
Lastly, the 360 in Japan, and NNK wouldn't sell enough copies on 360 to make it worth it in NA/EU alone.
it will do fine on the 360
Relations between the two companies soon began to spiral out of control as Level-5 struggled to meet the demands required by Microsoft, who in turn grew frustrated at the lack of progress being made on the game. After an extremely short and rather underwhelming showing at the Tokyo Game Show in 2003, True Fantasy Live Online was quietly delayed from its initial Fall 2003 release into 2004. From then, little was seen or heard about from the title, and after a surprising absence during the year's E3 convention, it was officially cancelled by Microsoft on June 2.
In the months following, Level-5 President and CEO Akihiro Hino stated in a Japanese interview that the poor relations between his company and Microsoft, partially due to the latter's inexperience in dealing with Japanese developers, was one of the major reasons behind True Fantasy Live Online's cancellation. He also heavily implied that the two companies did not part amicably.
