Well, this was unexpected! But, great news for Battlefield 3 fans with Xbox 360's. Patrick Liu, Producer at DICE has revealed that there is a second disc that will come with Battlefield 3 on the Xbox 360 that will contain a high-res texture pack that can be installed. Liu goes on to say:
There's a voluntary install on the 360. I think Rage did it as well, where you can install content to stream higher res textures," he said. "We're pushing that technology to the limit, and compared to our competitors, I would argue that we're the best looking game.
This is some great news for Xbox 360 fans, I look forward to seeing the difference between stock install, high-res texture pack and PC versions now!
