A lot of the content tooling for games is usually written in some other more productive language (C#, python, ...), so there is a lot of contact between managed and native even for AAA games, even though very little of what actually ships in the game is managed code. Getting a performance boost (or not having to interop) in a level editor, texture tool etc. will likely be welcome.
The tradeoff between safety/convenience/productivity vs. performance of C# vs C++ for example can't be motivated at the moment, and probably won't be with SIMD. Writing .NET code with deterministic performance is hard, so hard that C# is no more convenient than C++. I think any complex performance sensitive (Web browser, Game, SSL-Implementation...) is soon too complex to be done in C++ and too performance sensitive to be done in managed. Rust can't be released soon enough.
