HS-DHGL
From NAS-Central Buffalo - The Linkstation Wiki
Buffalo's new HS-DHGL "LinkStation Living" lineup sticks to the general HDD bump scheme, with options for 250GB, 320GB and 500GB hard drives (at the respective prices of roughly $287, $306 and $441), but spices things up a bit with DLNA for media pushing, and breaks new ground with iTunes server functionality.

It seems as if they are seeking to abandon the PPC/Freescale and MIPSel/IDT platform/processors altogether in favor of the system on chip ARM/Marvell processor.
The japanese verson of the firmware for this device is available: http://downloads.linkstationwiki.net/stock_firmware/hdh103b1.exe
