As of now, it appears that there are no more plans for Sting being used in TNA.  It's being said that his name rarely comes up as of late and the company has no interest in bringing him back.

Speaking of TNA, they are once again pushing for Rob Van Dam to sign with the company before Monday's live show, which goes head to head with Monday Night Raw, for the second time in just over three months. 

And the WWE just began production work on a DVD for Hall of Famer, Ricky "The Dragon" Steamboat.  The three disc set in tentatively set for a release date of late June 2010.
