ASUS to Unveil Phone/Tablet Hybrid?

At Computex 2011, ASUS is slated to unveil a new device that, as the teaser implies, "breaks the rules" by being a phone and a tablet at the same time. What could this be? One theory is that they'll show off a phone, like the Atrix 4G, which can be plugged into a docking station, or perhaps directly into a tablet (sort of like a cartridge). Another possibility is that they've come up with a device that can fold open to reveal a larger display, but can stay compact if you want to carry the device in your pocket (similar to the Kyocera Echo). The teaser image doesn't give us enough information to make a call either way. What do you think it could be?
