Rumor: Even more features for the new Sixaxis?

Let the speculation begin! Kaz Hirai has tempted us yet again with his fancy words and vague confirmations. He has let slip the new Sixaxis will contain a few more features in addition to the TouchSense rumble capabilities. In fact, he said, "a variety of other things." Unless he means the TouchSense. In that case, boring! Otherwise, we could see anything from a new set of buttons (L4 and R4, really?) or a remote volume control for game music. Maybe a microphone? How about a magnifying glass? We'd really like to see your most inventive ideas to incorporate into the controller, so why don't you go nuts and give us your "features" to add?
