Those fixes just change a few constant here and there. Any game programmer (or any programmer really) can do that with her eyes closed. The real problem is QA, user interface elements and internationalization. QA will have to do a complete walkthrough for every resolution * language * FSAA * videocard combination possible. This is very long and expensive. There will be bugs and they will need to get fixed. At the end they decided it was not worth it. Another company with different priorities might decide otherwise. But what I can certainly tell you is this was not due to limited knowledge from the staff.
