Due to the popularity of the Raspberry Pi and other boards like it, there was no doubt that many ore like it will be released, given the relatively low cost of production.
The latest one is called the Cubieboard. Compared to the Raspberry Pi, Cubieboard is loaded. The specs includes: 1G ARM cortex-A8 processor; Mali400, OpenGL ES GPU; 512M/1GB DDR3; HDMI 1080p output; 100M Ethernet; 4GB Nand Flash; 2 USB Host, 1 MMC slot; 1 SATA; 1 ir; and 96 extend pin including i2c, spi, lvds, sensors. You can even buy a simple, tranparent case for only USD $4.00.
With those specs, the Cubieboard can run Android and your favorite Linux distribution, which means that it can help turn your TV into an Android TV (output via the HDMI port), give you a standard Linux desktop computer, or a network attached storage (courtesy of its single SATA port and Ethernet port).

A limited number of prototypes have been sold, but a release date for the final thing has not been announced yet. You can get more info by reading the comments here and on the Google group.
Unfortunately, the audio ports are too close to connect them at the same time
