I'm thinking we will see a next year announcement with a release in 2013.
Xbox will more then likely include a Blueray as part of the build, PS4 I'm to sure what more they can add to their machines.
People like fast processors and betteer graphics but will they also allow backward compatibility.

- Elder Scrolls Online Tamriel Unlimited (PS4)
