Realize right from the get go that this could be as simple as someone at the ESRB clicking the wrong checkbox, but it certainly could be interesting. The ESRB now has there third listing for the game Gripshift. One for the PS3, one for the PSP, and now, one for the Xbox 360! Notice from the screen grab that the publisher has now changed to the developer of the game Sidhe Interactive. While I'm still thinking that this game is going to stay exclusive to the PlayStation 3 as it was published by Sony Online Entertainment, it certainly brings up some interesting questions about supposed XBLA/PSN exclusives. At this point very little is known about the publishing deals that exist between the platform holders and the independent developers. For instance, would it be possible to see some of the NinjaBee titles on PSN ?

Then again, this could be mush ado about a typo, we'll let you know when we find out more.

[UPDATE] It seems that this has been a possiblity for a while and shouldn't be taken as any sort of supprise or coup against Sony. Here's a quote from an interview with Mario Wynands of Sidhe from IGN back in December:

MW: We are currently investigating digital distribution across multiple platforms, but for now are focused on delivering and supporting GripShift on PS3.[/quote]
