I think it's called the 346, I was looking around online the other day and noticed its been released by DLink in Europe only, the difference is the new one has iSCSI which is major piss off as DLink should have made iSCSI available in the 345 to begin with.

For some reason I doubt they will be released in North America anytime soon!
