It is possible, that it works out in some markets, but the european market is saturated. Especially germany has really flat mac sales (under average) compared to other countries like Switzerland. It has been discussed in other threads, that macs seem overpriced in countries outside US due to currency fluctuation and high taxes. Why should the new price structure help sales, when people already vote with their wallet? I mean the upgrade costs 600 = 811$. And they killed the entry 15'' cMBP for 1700. So they basically raised the price for a 15'' Macbook with a dGPU by 900 = 1216$.
I'm sorry, but your argument does not convince me. I don't think it will work out: the unusual high discounts are an indication, that the new model is not selling well. The trick last year was far more subtle: if you added an SSD an RAM to the base 15 cMBP, it was cheaper to get a base rMBP. I wait a few more months with my next purchase, because expect a price drop next year (like the price drop of the 13'' rMBP this year).
