Not my case unfortunately but I've been tracking some of the cases filed on 10/01/03 and noticed that one was approved today (I'm pretty sure it's status was "received" yesterday -- no RFE involved):
Don't know if it's EB2/EB3 etc. nor whether it's a concurrently filed case, but the case # is EAC0400152097.
From the online status:
