Belkin is at Computex 2012 in Taipei showing the world its updated Thunderbolt Express Dock prior to its release this September. The new version will feature a pair of Thunderbolt ports (one for connecting to your laptop and another for daisy chaining more Thunderbolt devices), three USB 3.0 ports, a FireWire 800 port, Gigabit Ethernet, eSATA, a Mini DisplayPort to HDMI adapter, and audio in and out. This is the third iteration of the dock, which we last saw at CES, and has yet to be released. The differences between the previous model and this latest proposal are the switch from USB 2.0 to 3.0, the removal of a dedicated HDMI port, and the addition of an audio-in port.

Somehow, the changes have bumped the price, which was already hard to stomach, from $299.99 up to $399.99. The dock is still on target for release in September this year, but Belkin has also announced a three foot Thunderbolt cable which will go on sale for $44.99 next month. Matrox announced a Thunderbolt dock yesterday that undercuts Belkin by $150, so if daisy chaining devices isn't a must for you, it's pretty clear which offers the best value.
