Will the IPhone 6+ come down in price before christmas?

I have an O2 lease contract for my phone and I'm wanting to get the IPhone 6+ but it is too much money. My contract ends just before Christmas and I'm just wondering if it will come down in price. For example at the moment it is £35 a month but £99 upfront cost. I'm wanted at the most £30 upfront cost and at the most £35 a month will it come down? Or if you don't know do you know if the 5s came down when that was released?
