No More Firmware Updates?

I sure hope I’m wrong, but it seems that with the release of the new NAS drives from WD the old EX2, EX4 and Mirror will not be seeing any further firmware updates.  Has anyone heard of any upcoming releases for these units?

I would like to know this as well.

Has WD abandoned the driver support for EX2-4 users.

No fixes or new features for our firmware?

Perhaps WD would be willing to offer some sort of trade-in allowance for these?
