Not sure if this means anything but:
\kbdupgrade-3.0+svnr5493\src\kbdupgrade.c
Code:
static char *device_types[] = {
"DR1000",
"DR1000S",
"DR1000SW",
"DR800",
"DR800S",
"DR800SG",
"DR800SW",
NULL
};
Given the obvious nature of their naming scheme, this may not indicate any future products. I would be more excited if there were a DR800SGW.
