I looked around and it seems like this is being listed as clearly a rumor, I don't like that no one actually has the Famitsu pages to back up this kind of information. The information about the colored Wii's accompanying Brawl in Japan and coming with Two wiimotes + nunchucks seems to be under scrutiny too. All of this stuff seems to be falling too far under the realm of awesome, or in other words too good to be true. RPGfan seems to eb reporting it as fact though, even though everyone else is sticking to rumors:
Star Ocean 4 PS3, 360-Bound
12.11.07 - 12:54 PM
The newest installment in tri-Ace's flagship Star Ocean series, Star Ocean 4, has been confirmed to be in development for PlayStation 3 and Xbox 360. The newest addition to the critically acclaimed franchise is apparently too big for one game, so developer tri-Ace decided to split it up into the following three episodes: Star Ocean 4: First Departure, Star Ocean 4: Second Evolution and Star Ocean 4: Till the End of Time. Series fans should recognize the subtitles as being the same for the first three games of the series (the first and second subtitles being newly added for the PSP remakes).
Star Ocean 4: First Departure will be available in Japan sometime next year.
