On most game system perhaps, on DS I doubt the majority is real-time. I wonder how many units sold for turn based game like Civilization IV, King's Bounty the legend, some FF released on PC and more. That said if I would be very interested in a sort of Din's curse turn based, in term of design it's a totally different challenge to design an action game and a turn based game.
