I see no mention of pci slots.
Despite the Kuro's young age, it seems that there are already thoughts about a Kuro II. Possible improvements could include more RAM, a faster processor, a serial port, another USB port, and even a Mini PCI slot. Choosing a newer Freescale processor with more integrated IO could even reduce the development cost, since fewer external chips (ethernet, USB, ATA) would be needed and board complexity would be reduced.
