TBH, Q10Pro is performing very good for its price. The eventual option of Dolby Vision decoding is still attractive 
i echo that.
for the price and what i use, it is excellent; firmware 2.0.8 is the best to date - for me.
i read a lot of complaints about subtitles but my collection with ext subs which is not a lot... srt, idx... been good since 2.0.4.
embedded subs, incl bdmv have never been a problem for me.
what i use this box for:
.. local playback of typically larger files - 1080p/4k bdmv, dtshdma, ddruehd; i don't do 3d and have few old dvd rips; no gaming.
.. i never use kodi for local playback, i like it fast using native player; wrapper not in use.
.. kodi... using only one addon - quasar - this one works very well with internal hdd - stream 5-20gb files with dd/dd+ (not dts) audio since 2.0.6.
.. a few live tv and vod apps - in hd, incl a couple that did not work with firmwares 2.0.7 and earlier.
.. samba play or transfer files from pc to box sometimes.
as it is, i find q10pro good. i just wish himedia will do is to introduce a new model with octacore 3/32gb as i plan to get another box.
that will reduce the need for int hdd for some apps, a lighter box and hopefully, cheaper.
quadcore 2/16gb is already obsolete in mobile phones!
