$1800 for 1600X1400 on a 14inch display? I LOLd
What does that have to do with the price of tea in China. 95% of people utilizing Retina display have no idea what retina resolution actually means. Secondly the majority of people are using some sort of scaled resolution for their rMBP's. And last, 100% of people using rMBP for gaming are doing it with something other then the retina resolution, why because no GPU can drive anything that res with decent FPS.
The price might be high but many people just hate Apple and this is their way of owning something can do the same and more, and still portable. Retina displays are amazing, but is it really required? This laptop will sell, and it will have a cult following just like apple does. 2 different spectrum's of the scale, and I'm sure it will do quite fine.
