Whither Zherdev?

Well, with the acquisition of the perhaps more electric RFA EnverLisin

http://www.youtube.com/watch?v=cnspXe2h3xw it seems RFA Nik Zherdev is gonna be gone soon. Now, the question is will the Rangers be able to combine him with Redden or Rozsival for a good piece or will they just renounce their rights to him and make him a free agent? I would think there's another deal in the works, and I'd think it will be announced soon, though I have no idea what it might be for. Go Rangers!
