I'm pretty sure there is no windowed mode.
There is another patch coming, though probably not too much before the add-on is released (about September). With changes, fixes and balancing still being addressed in the main game, the beta testing cycles for the patch and add-on may get combined, to save on time and resources. Microsoft in particular has limits on the size and number of patches for Xbox games, and I doubt PC publishers would be thrilled about having to redo the beta testing if a patch were released significantly before the add-on.

Blur effect:
My friend, I had the same problem with you. Annoying sun effects and kinda blurry graphics on dialogs screen.
Your solution: In the options - graphics menu, if you go down with the arrow keys you can see lots of graphics options (which can be very difficult to find first time). Remove the tick from "render shaft lights" then puff annoying bloom problem is gone. If you want also sharp graphics in the dialogs, remove the tick from the "depth of field". Play & enjoy.
