No, they won't make PS3 version because
It's a SONY
Hate to ruin your day but the original arcade Idolm@ster used a Namco System 246 - which is a customised
SONY Playstation 2. Source.To rub it in a bit more, as that was the original, that means it was first designed and made for
Sony and then ported to the Xbox.
Good luck with your
Sony hating
