Finally took the initiative to read a chunk of the interview/skim for nice things. Props for this:

"Well, we can’t make any specific announcements, but we do have some great games–classic and new ones alike–coming out in the next few months. Make sure to keep your figurative ear to the ground for more updates from GOG. "

Yeah. I'm surprised they wouldn't use DOS for this, unless they expect many complaints about a non-Windows version (like Simcity 2000).

Do you know if the Windows version has something the DOS version doesn't (like CD audio)?

Great read.
But in my opinion, as it was said (kind of) : 80% redux and bundles bring more harm than good to the big picture.

As I recall, the DOS version has a low res (320x240) and a high res version (640x480) much like Dungeon Keeper does. I guess the high res version couldn't be made to work consistently, so they are trying to fix it. Sure, you could use scalers to increase the resolution, but that is not the same as using a higher resolution to begin with.
