MacTech has the news on these new Thunderbolt Docks.
It features:
15 ports: four USB 3.0, one Gigabit Ethernet, one FireWire 800, one headphone, one microphone, one speaker, one audio in, one pass-through Thunderbolt (for either another Thunderbolt device or an external display), two eSATA, and two internal SATA (one port for included optical disc drive and one 6 Gb/s port for a user-installable 2.5-inch SSD or 3.5-inch hard drive). In addition, the Echo 15 Thunderbolt Dock includes an 8x DVD±RW drive, or optionally, a Blu-ray BD-ROM/8x DVD±RW drive with Blu-ray player software for OS X
They range from $349 to $549.
Thunderbolt products are still a bit too expensive, but this is pretty impressive, especially since you could hook up a new MacBook air to and have a pretty impressive desktop machine (sans a serious video card).
