Amazon stopped updating the K1 pretty much right after the K2 was released. I think the K2 has gotten one update since the K3 was released. There was rumor of a DXG update recently but I never got it, admitidly I didn't go looking for it but one would think that updates would be sent to everyone.
I think that BN will support the Nook Classic in it's current form until there is a Nook Classic 2. I would be surprised in the NC1 is supported after the NC2 is released.
