I must agree with some people that making a model "perfect" is almost impossible. I don't know when the unrealistic situations happen, but they're probably rare. I don't see why a test or alpha patch cant be released to give (after 2 years of delays) a taste of the new physics and content. It's not a official patch and people can't really whine and neither. I believe Scawen is afraid of people getting a bad image of unfinished physics and damaging future sales.
