Looks like native MKV support coming with windows 10 for phones..
currently ms added native mkv support in windows media player in desktop w10 preview as well as in xbox one console.

Positive we will get this feature on RT and WP as well in W10.

Yes, this is what they did. I played an MKV file on my Surface RT using the built in "Video" app after installing the update last night.
