Looking at how Ubisoft is handling their business lately I doubt they will last another couple of years. If they were to go out of business people would no longer be able to play MMH6 (or they might still be able to access it in offline mode without several restrictions).

My question is, will there be a DRM-free version MMH6 from GOG some day? Without any of those Conflux, always-online crap? For a hardcore fan of the series, MMH6 is without a doubt a slap in the face, but from a collector's viewpoint I still want to own a complete collection of HOMM series from GOG.

Go here and vote, post a comment and so on.
But why we ever need such a crap here on GoG?

P.S. Remember that Heroes V and MMH6 have absolutely no relation to HoMM series by New World Computing.

At the same time, HoMM5 is MUCH better comparing with "HoMM6" that is real slag indeed.
