The next patch will improve the graphics and add more graphics options, among other things.

Posts about the game content (plot, quests, etc) should either be enclosed in spoiler tags or go in the Help/Tips/Tricks forum. The majority of people following the main D2:ED forum have not played the game yet, and do not want to see any spoilers, especially about the end of the game (even if it is just in general terms).
In any case, presumably there will be a Divinity 3 to finish off (or continue) the story started in Divine Divinity, the Beyond Divinity novella and game and D2:ED (the BD novella and some other background info is included in the D2:ED fansite kit).

The German publisher signed on relatively early (a couple years ago), while the English / international publishers have not been announced yet (we expect / hope for an announcement during CamesCon, where DTP will be showing the game, so in the next 2-4 days we may know more).
The German version of BD was also released a month or so before the English version, IIRC, so the English release included updates from the first German patch.
