Belkin upgrades its Thunderbolt Express Dock before it's even available

At $399, this is a lot pricier than the $249 Matrox DS1 Thunderbolt dock we saw yesterday. That said, it'll bring superior connectivity when it arrives in September -- not least because Belkin has improved on the design it previously showed off at CES. There's Thunderbolt in and out to allow full 10Gbps daisy-chaining of further peripherals, alongside FireWire 800, Gigabit Ethernet, Mini DisplayPort (with included HDMI adapter) and audio in and out. As of the update, eSATA and three USB 3.0 ports have also been added to that healthy list.
