SGMiner was an awesome miner, even CGminer.

There was development last year by wolf and GenesisMining which ported the SGMiner to include the older version of Cryptonight.

However now with profitability down the drain and people losing interest, I don't think we will see an updated miner anytime soon. Maybe if things start to pick up we might see a Claymore V8 miner and a SGminer which supports V8. Until then, all we can do is wait.
