Microsoft would never say for sure.

And you're discounting company-internal products that were built in the 95-98 era, then updated when new business regulations came out, but were never rewritten in a modern language and the company wouldn't spend time and money to port them to Windows 9 when they worked fine on every previous version -- they'll just wait until a newer version of Windows fixes the problem or Microsoft very forcibly drop support for 8 completely.
