Lots of patches means lots of money not spent on developing the game. Let them only do it when they have plenty that needs new EA input. Remember as well as the direct cost to Larian in providing the patch (development, editing for EA and QA), they also have to pay Steam/whoever for the privilege of the download. Steam/whoever aren't going to provide all that storage and bandwidth for free and they can't monetise patches (yet).
I would prefer all that EA money go to development rather than some quick content just to please a few forum-goers. Don't get me wrong, I'd love more content, but I know resources are finite.
