Depends...
IF he stays out of prison and, if so, how much it costs him to do so. IF this results in money problems AND WWE are prepared to take him back then I think we'll see him back in the 'E. (Although you gotta wonder how many more times WWE are prepared to give him a-n-o-t-h-e-r chance...)
Honestly, Jeff Hardy was one of the guys that I thought could maybe have the right impact (no pun intended) on TNA and their ratings, but they couldn't even give him a decent debut let alone make good of his presence once he had arrived.
