you will probably do far more extensive testing for the next games, and remove every other way of doing things
More testing would be nice, but I doubt it would result in fewer ways to do things (other than possible exploits that could break quest flow). In fact, if they have enough resources for additional testing, then more will likely be allocated to quest design, etc, giving more freedom.
The next patch will contain some engine optimizations, though I don't know if that will fix the stuttering problem some people encountered.
