I can highly recommend the interview with Jason Gregory of Naughty Dog from Handmadecon 2016. He gives a lot of insight into the reality of working with the scheme-based format in recent-ish times.

My impression isn't that scheme is being passed out just because Sony doesn't like it, but also because the language has issues. On the other hand, it seems they're putting a lot of effort into getting the nice scheme features, like hot reloading, in their C++ environment.
