48 Hours to Trademark Lawsuit

48 hours to produce the first issue of a magazine. An ambitious goal meet by a few friends and 1000's of content contributors over a weekend in May. 48 Hour:Hustle, a print on-demand magazine, was started on May 7 and issue zero was  wrapped on May 9.  The cease and desist letter from CBS Broadcasting, Inc. was received May 11.  (I calculate 48 hours between release and demand letter...irony).

CBS owns the trademarks for "48 Hours,"  "48 Hours Mystery," and several other similar marks with "48 Hours."  The CBS marks are in Class 041 for a television series.

Would a consumer be confused that a magazine named "48 Hour:Hustle" was from the same source as the television show?  I also wonder if an argument could be made by another trademark owner for likelihood of confusion with their mark:  Hustler.
