[...] Divinity 2 is following the pattern of all the videogames which are produced with only the German market in mind [...]
Which games would that be? If you're referring to Drakensang - that's based on a German role-playing system that is mainly popular in Germany, and the game was produced in Germany, so it's quite understandable that it was produced with the German market in mind. Apart from German games,

is one of the very few games the German version of which is published before the English version. Often enough, it's the other way round.
According to a press release from May, the English voice recordings were finished. Larian never said why the English version is delayed so much, but to me it seems highly probable that it could have been published together with the German one - if the English/American publisher had agreed (or if there had been an English/American publisher at that time).
I fully understand that you don't like the delay and the lack of information, but I can't see the "pattern" you're talking about.
