Public transportation in Apple Maps

Hi everyone.

Has there been any indication of Apple implementing public transit guides into Apple maps both desktop and mobile?

I travel by bus and train every single day to the university as well as my job. My calendar is always fully updated and everything has addresses written in the calendar. It would be rather nice to just click the address in my calendar appointment and then be sent the travel-time and schedule instead of being booted to a third party app or in the case of the desktop nothing at all.

I know that it is probably a minor inconvenience in the greater scheme of things. I was just wondering if, there has been any rumors or acquisitions that would indicate them working on it?

Have a nice day, everyone
