I would personally prefer the current business model, where each patch includes bug fixes *and* new content (but mostly bug fixes and balance improvements), and have them work on a full-price Dom III for the next paid Version.
An expansion would have to include a LOT of new stuff to compete with the new content we're given for free with each new patch.
I don't think your idea is stupid, tinkthank - I just think that with an INCREDIBLY small business model, the fact that this is the "labor of love" of only two developers, and the lack of a giant marketing structure like Blizzard or Microsoft have, the current way of doing things is probably the best for the customer...even if you don't feel like the bugs which affect you are getting fixed as quickly as you'd like.
We'd all like to see faster/more frequent bug fixes...but that goes for the expensive, highly-marketed, expansions-cost-$30 games I have played, too.
