Wes Littleton has been traded to Boston for cash considerations or a PTBNL.
Jon Daniels is saying the PTBNL may not be named until sometime in the spring. My guess is there is a list of guys the Rangers will get to choose from, and they'll spend the winter and some of the spring scouting them.
UPDATE -- Some reports say a PTBNL. Some reports say two PTBNLs. I shall seek clarification.
