Hello @KK2013 ...
Unfortunately, I do not have an answer for you. I actually do not work for Instructure (the folks who make Canvas). I work for an arts college in Detroit, MI. Although I do know that Instructure is not implementing any new features for Classic Quizzes, I know that they have been working on the New Quizzes interface. I am not sure what they are currently working on or what specific plans they have in place for down the road. However, I can point you to this:
New Quizzes Hub - Instructure Community
You'll find a "Product Roadmap" section on this page where you can at least get a general idea of what is coming down the road. Also, I suggest (if you are not doing it already) that you follow the monthly Canvas Release Notes...as sometimes you'll see updates and enhancements to New Quizzes in those documents.
Sorry that I cannot be of further help, but I hope what I've shared above will be of some use to you.
