Pocketpair recently posted the following roadmap of new features to come. How quickly will they be implemented? See also my other markets for different resolution times

Each feature resolves YES if there is a playable update containing the feature before market close. Resolves NO at market close otherwise.

I don't really know what "Xbox Feature Improvements" really means (I don't have an Xbox. Is there something wrong with the game on Xbox) but I will be very liberal in resolving it to YES.
