Seriously, though... How many "standard" formats does any given device need to support? I wonder if they'll release players or update the OS to accommodate new "standards"? Seems feasible?
I don't think that would be the deal-breaker by any means. ...
No, this time it is... When my 18TB library is all HD Encrypted versions of my private DVD/BR (no, no pirated content allowed in my library...) collection in MKV format because it's the best version to use for every other device out there and M$ refuses to use it... That's a deal breaker. Heck my phone even uses it for goodness sake.
If they only supported four formats for video, I would think it would be .avi .mp4 .mkv .wmv. But the problem is for now, .mkv is the only container really supportive for full HD (blu ray) H.264 video with full chapter, subtitles, etc. .mp4 is close but... actually you can take an .mkv file and rename it .mp4 and it will play but you lose some of the functionality.
The simple fact that M$ has put their hoof down on the wonderfully powerful .mkv container is really annoying, especially when my whole house is loaded with HTPCs and I have to use two programs to feed the media instead of just using media player which would be nice.
For that matter, they should also support FLAC lossless audio as my entire CD collection is also on the same library that way. So audio gets played with Winamp, Video with MPC-HC, and TV with Media Player on each HTPC. Once it's all configured the user can't tell the difference but it would be nice if they never left the media player interface... or could use the xbox. But as it sits, I'm not getting an Xbox One or PS4... Same reason I didn't use my 360 or PS3 for the last many years...
So is it a deal breaker for someone like you who probably buys it to play games (although I wouldn't bother playing games on a console.. I just can't stand the sticks honestly... Although I do have a medical issue there also... another story...). Probably not. But for someone like me who would be buying it strictly as a media box for my already existing library, absolutely it would be a giant deal breaker. Enormously huge, tremendously #1...
It would be like an enormously heavy set man looking for a sports car. Well, can't buy a Ferrari simply because he can't fit in the door.
I was already bothered by the fact they didn't say how many tuners the TV tuner had (3,4,5,etc... Does it use a 3rd party like the Ceton USB 4-port unit, etc.) does it use local or remote storage for DVR, can it off-load DVR to remote viewing (something HTPCs have issues with in Microsoft ATM). I was actually really excited about it for awhile. But then they didn't get into anything but garbage in the live broadcast... 'Ohh, look at my hand gestures'... Or, could I even change saying "Xbox" to "Computer" (Comon, Star Trek wins over Micro$oft Every single time... plus to me it just makes more sense really.)
There is still time though, maybe they will add these features as well as some container support. But if not, that's at least one sale gone.
But as for your question, how many should they support, Honestly, if they want to make it intended as a media control center, then ALL OF THEM, to be honest. But as a minimum, all of the most common. FLAC, .MKV, .OOG, etc. to name a few. If that's their intention, do it.
