To tell the truth: I hope we won't see the extra version of update 14 here (at least not before v15 is out). But if it happens, it happens ^^
The dev tolerates the sharing of the 720p version (which is also not free) and even was active here in the past to help and get opinions (he stopped that, probably because of repeated sharing of the extra version).
Of course, we all know he couldn't do anything about it, until he doesn't add a very restrictive DRM system on the game (which he doesn't want to do, as far as I know).
So, maybe somebody will share ep 2 v14 today, maybe it will happen never (in that case I advise to wait until the final version of episode 2 and to spend some bucks then to get the full game for only 1 payment).
But DM won't share the Extra version on his own here, sorry.
