We all know that the Apple Watch isn't selling in iPhone numbers, but by all intents and purposes it is selling well compared to the rest of the market. There is no way that Apple will reduce the price of the AW before Gen2 arrives. Then I do forsee then reducing the entry cost significantly (as much as $100 less). What they will probably do though, is reduce the Sport models to $249 and $299 ($100 less than the new v2.0 Sport models). They will also discontinue the Stainless Steel and Solid Gold models for v1 as may even use the same form factor for these models to implement the new circuitry.
I still believe we are talking an 18-24 month cycle for the Watch, so we are talking fall 2016 at the earliest, but possibly Spring 2017.
Although they won't reduce the main RRP of the models, what they may do is introduce a financing model or reduce the cost of some of the bands.
