I share the same sentiment. I honestly thought that the price increases would occur as new products rolled out. Seems like with the "back-to-school" promotion right around the corner, Apple expects to sell more machines and find it harder to absorb the higher component price tags. I'm guessing that by changing the prices now, they'll still maintain their profit margins per unit at the expense of total unit sales.

Maybe they don’t want the price to absolutely dominate the headlines of their forthcoming product announcements. It won’t be forgotten, but the sting will be less “newsworthy”.
