Are people just worried about the price because of the 'pro' name? Apple always puts new stuff in and doesn't raise the price. Retina screen, Touch ID, massive increases in CPU/GPU performance, laminated screen.
I don't see where the justification for a price increase comes from just for a new chip (again) and a slightly different screen.
They want people to buy keyboards and pencils which will make them a *ton* of profit. They should keep the pricing the same. Maybe even adjust the big pro down by $100 as it doesn't appear to be shifting many units given the discounts available.
Of course in the UK we'll probably still see a price increase due to the stupid exchange rate.
