Gone is the touchscreen in the middle but there are more buttons for you to press. Valve just sent us a picture of the new Steam Controller and it will be available at GDC to get some hands on with.
The left is the new model while the right is the prototype that was shown a while ago. There are some subtle and big changes, with the buttons and lack of touchscreen being the biggest alterations. Videos shown have made it look like a solid performer. Needless to say, I can't wait to get my hands on one.
