BeagleBoard.org has announced the BeagleBone, a US$89 smaller version of the BeagleBoard. Based on the new Cortex-A8 TI AM3358 SOC, the most obvious difference is large expansion connectors with 0.1" pitch. (Why don't they use 2mm pitch? You get 25% more pins and can still wire-wrap.) No direct video output: instead you get the interface signals to do whatever you want using an expansion board, e.g., HDMI, VGA, LCD. Built-in USB JTAG using FTDI chip.
They haven't announced how much DRAM yet. BeagleBone uses separate DRAM instead of package-on-package, and has a wide pitch BGA for the processor.
