movie rentals over iTunes for weeks now. Now it would appear that Warner Bros have joined Disney, Twentieth Century Fox, Lionsgate and Paramount in the initial launch. This, according to sources speaking anonymously to Bloomberg. The announcement is expected to be made on January 15th according to the report, presumably during Jobs' MacWorld keynote. Both new releases and older titles will rent for $3.99 for 24 hours. Bloomberg's sources also indicate that Fox may join as a supplier of movie downloads. While the details may change, an iTunes rental service announcement on Tuesday seems a near certainty given the recent multi-source, confluence of data.
