I can sum up how I feel about this in 1 word FINALLY!!!

It's an open question why the code mentioning the game controller support status is already pushed out to the live app store web pages, but we believe that keeping the changes hidden isn't much of a priority anymore because controller support has been announced as of the keynote. Still, this feature was heavily requested for years, so we think it is noteworthy.

Happy to discuss this and any questions in the comments!
