Soo.. what exactly is new and don't say .MKV cause that's supported now with AAC audio, just not AC3 which btw isn't listed for BB10 support either. Unless I'm missing something, it's almost identical to what we have now on the Tablet OS. The things I see different are some audio codecs like MIDI, OGG and Flac and even some of those were already supported through Flash libraries and such.
