'Dear Zindagi' and 'Kahaani 2' avert the big box office clash?

Big films clashing at the box office seems to be the new trend in town. After the big clash of Karan Johar and Ajay Devgn's big Diwali releases, it was said that Shah Rukh Khan starrer 'Dear Zindagi' and Vidya Balan's 'Kahaani 2' will also have a face off at the box office.
But according to a few reports both these films which were slated to release on November 25, Vidya Balan starrer 'Kahaani 2' will now release next year.
Reportedly, 'Kahaani 2'is complete but the truth is that one song and some patchwork is left to be shot in West Bengal which will be completed once Vidya returns to India from her US vacation in October. Therefore, director Sujoy Ghosh and producer Jayantilal Gada are planning to release the film early next year.
