Sortof, but the Chinese generics are crushing most them in profits. The market forces that are driving the mergers are the same ones that are making things so much better for small and medium sized OEMs. Only the largest OEMs have anything to worry about. You could actually end up with a situation where the largest batch sizes actually more per unit than regular-large quantities! That could happen when there are only a couple mega-suppliers left that can even fill the big orders, but there are a zillion factories offering regular sized batches. You can only get quantity discounts up to the max output of a single supplier; then past that you're paying extra for somebody to scrape together the different batches. And if you need matched parts, then you're paying high prices.
Losing NXP will be a big hit for the small designer, because they sell lots of great chips with quality, easily accessible datasheets. Qualcomm sells expensive chips to exclusive buyers and they protect datasheets as if it is their private laundry. But the overall effects of the mergers might be good for the little guy, mostly because it is a battle that the medium-sized Chinese factories win in the end; and they sell to anybody. And they'll include the datasheet when they have it.
