Pretty much. Though they've periodically updated them to use new techniques like animation blending. I think there's also a lot of work in optimizing for different platforms. And perhaps more importantly, there's a lot of work in making the middle ware easy to integrate. Ease of integration is often more important than performance for a lot of middleware. I've seen their logo on tons of games. I never knew they were a local company (Kirkland, WA near Seattle).
