There was an exhaustive topic on this--but the answer is no. At least not in the near term. The 752s, 738s, and 73Gs are the only Continental birds that you will see with winglets; and at present the entire fleet of those aircraft will not be receiving them. They may out fit the entire 738/73G and 752 fleet with them down the line though. The 753 and 739 are for high volume/low yield domestic/Mexico/Carribbean/Latin American routes--so no winglets.
