The least we would expect is for them to announce an unexpected end-of-life themselves. However, Trend Micro released a security advisory today describing two zero-day vulnerabilities for Quicktime for Windows, and according to them, Apple told Trend Micro -- but apparently nobody else -- that they have deprecated Quicktime for Windows and will not be releasing a patch. The Register has an article on the announcement. Apple did not respond to their request for comment.
