Based on an Elon's interview with cnbc (see link below), the best guess is the model x will range from 60k to 85k (after 7k incentive if it still exists). So the 60k would be for a no frills 60kWh. Following the pricing of the model S, then the 85kWh would cost 70k and the performance 85kWh would cost 80k. To get to 85k I believe that this is the extra cost of the second engine for AWD. So for the AWD versions,the cost would be 65k, 75k for the non performance models. I imagine all these prices go up as you add paint, tech, high quality audio, etc just like the S. The two things I can see throwing these projections one way or another is the loss of the 7k incentive and/or the improvement/cost ratio as batteries improve. Also note the interview below gives us range of expectations of 220-270 miles per charge.
