The crew over at 360sync discovered that Microsoft's press materials for Conker: Live & Reloaded and Jade Empire have been recently updated. Now, that wouldn't be all that newsworthy if it weren't for the fact that both games are backwards compatible and Microsoft's press materials usually only get touched when there is news about the product being announced. So, so our speculative thoughts lead us in the direction of the Xbox Originals program.
It isn't entirely crazy to think that Conker and Jade Empire could be making the Xbox Originals jump seeing that both studios (Rare and BioWare) have tight connections with Microsoft, but it's far from being set in stone. And to be fair, while confirming Conker and Jade Empire's updated materials, we noticed that the press materials for Rare's Kameo and Perfect Dark Zero were also updated the same day. Take the rumor for what it's worth.
