No one can give you a definitive answer except ICAI. Surely the institute will come up with the roadmap very soon to put to rest all speculations, so you need to have patience until then. However, since your attempt will be in 2017, you should start updating your knowledge on many things that keep taking place around us. The CA course is not about just preparing for Examination, its beyond that.
