It's unlikely that QCF will do something like this. If you look through Nandrew's and Dislekcia's posts, you'll see that their next project is going to be a Naga-themed dating simulator tentatively named My Skin and Tears: I Shed Them Both For You. It was originally going to be a mini-game contained without DTD as a reward for completing Naga City 100%, but they decided it made more sense to develop it separately as a spin-off project. I'm a bit leery of the whole thing, and the furry (scaly?) thing kind of puts me off, but I still wish them the best.
