His point is that many studios nowadays use an established engine and do not develop in the C++-from-scratch-style. Especially smaller studios do not have the capacity for this and also depend much more on cross-platform availability to generate more sales. So they use Unity or stuff like Gamemaker Studio and use whatever binding is available (C#/Boo/Js for Unity, Gamemaker Studio has its own language). Or they even turn to something more exotic, like Haxe/Heaps.
