Even before it is released, Belkin has announced an update to its Thunderbolt Express Dock. The unit is mainly aimed at notebooks, sporting many more connections than a portable system would normally support. The upgrade mainly brings in three USB 3.0 ports, in place of the USB 2.0 ports Belkin originally announced. The company has also added an eSATA connection, which should please Windows laptop owners. Other ports are two Thunderbolt ports — one upstream and one downstream — as well as FireWire 800, Gigabit Ethernet, MiniDP-to-HDMI, and separate 3.5mm in/out options.
The add-on should ship in September, while the price has gone up $100 to $399 beyond the USB and eSATA connections. In July Belkin will ship a $45, three-foot Thunderbolt cable, capable of daisy chaining up to six devices.
