If anybody is interested I just finished the game and made a detailed report for the WSGF (Widescreen Gaming Forum). Of course, the report deals with the way the game behaves in widescreen. I'll first give you a fast overview and if anybody is interested or wants to see widescreen screenshots they can click on the link below.
The game can be played in resolutions with the 4:3, 16:9 and 16:10 aspect by selecting them from the launcher menu; I finished the game on 1920x1080. The support for widescreen is native, but the way it's implemented is not perfect. The game is mostly vert -, so that means that the top and lower part of the 4:3 image are cutoff to make the image seem wider, although there is also a little bit of hor +, meaning that the horizontal view increases slightly. There is a couple of few other small inconveniences: the HUD, menus and loading screens are stretched and the projected shadows usually are not displayed at all in widescreen.
