Those who purchased the Sound Studio Package were supposedly getting more on-board system storage vs. non-Studio optioned vehicles (I believe 16gb vs 8gb). That extra storage was supposedly allocated for media... the Studio optioned vehicles are not caching more map tiles than any other MS as far as I can tell (anyone else?).
So no; they've made no such statements as to how that extra storage on Studio optioned cars has been/or will be used as far I can find. Did Studio cars actually not come with increased memory on-board? Maybe all cars came with 16gb system boards?
... and playlists and shuffle are not hard to add to a Media Player. However they have the time to develop Name your Car, iOS Calendar integration and "Traffic Commute Advice"; useful to some, however I expect the majority of us would like a decent media player first.
Is it possible there's a system limitation and we might never have the basics like playlists, shuffle, etc?
If it's not every going to be available, they should come out say so... and maybe send those who ordered the Sound Studio Package an 8gb Tesla USB drive... or at least something?
