Where did you get that feeling from? Wind turbine manufacturers are engineering heavy organizations. The competition is fierce. Only those manufacturers with the best R&D have survived. From time to time you see radically new designs that never get anywhere because they are just so much worse than the 3-blade design that won out. The main development area right now is probably floating foundations for off-shore turbines. Residential-scale wind turbines are difficult - they need good height, require maintenance, are noisy. They are a niche product. Yet, there are several manufacturers, and again competition is fierce.
