Eternal Sonata Not a 360 Exclusive?

Well, it seems like the ESRB has possibly made another leak. Either that, or someone just checked the wrong box when posting something.

Joystiq got word that the listing for Eternal Sonata on the ESRB ratings list shows both the Xbox 360 and PS3 as platforms.

Is this an absolute, undebatable confirmation that it will be released on both platforms? No. Is it a likely indication of such? Yes. The fact that the PS3 is outselling the 360 several times over in Japan isn't open for debate. Everyone knows that the Japanese love their RPGs, so it's a pretty logical step. Of course this listing mentions nothing of Japan, where the ESRB isn't followed. So perhaps it's only a multi-platform game in North America...

If this ends up being true, I guess it proves that non-exclusivity can flow both ways.
