As pointed on Impact, Abyss hasn't been seen since his Monster's Ball match with Bully Ray at Genesis. As pointed, Ray did attack him, but lost sight of him afterwards. His family (which I thought he killed or hated) sent a letter asking for him. It seems they are setting up for his return. But what will his return be about? He already beat Bully Ray in a Monster Ball match so there is no real reason for him to go after Ray just because of a small backstage brawl. It puts both Ray and Abyss on square one again. Maybe he'll be joining Sting in his efforts against Bully Ray, Bobby Roode, Austin Aries and other guys that dislike his ruling on TNA instead. With Lockdown coming by and zero stables around, I guess it would be ideal to have Abyss to fill the face ranks. Speculate here on Abyss' possible return I guess.
On a side-note for the uninformed, he was written off so he could work at Ring Ka King.
