I wouldn't say Stern doesn't care....but the only way to change NIB games from having incomplete code or lack of updates is to quit buying NIB games from any manufacturer for the next 3-6 months and make it known that is why people are not buying. It will never happen but if it did we would see more code updates real quick.
Operators used to be the majority buyers and they did not care too much about code as long as the games earned. That has been the norm for the industry. Now that home/collector market is becoming majority of sales it is becoming an issue/complaint. The problem is that people are still buying games so there is no push to change this.
Keep in mind Stern is in business to make money. If sales slump and their market research says its because of code then they will take action. Each title they produce has projected target numbers/ revenue. Once those numbers are reached life is good.......There may not be enough ROI (Return on Investment) to allocate "dedicated" resources to update code for a game that has reached profit margins. Now for a game that tanked they may realize code can't fix it and move on. If code can increase sales it only makes sense to update it because the license and development is already done.....they are not going to leave money on the table and Kiss sales definitely hurt due to incomplete code for sure......
I believe we will see an update for Kiss but who knows when. I think Stern has bitten off more than they can chew at the moment. They have a very aggressive production schedule with 3-5 titles / year. They are spread too thin with developers/programmers working multiple projects to meet production schedules. Add in the issues/delays and Stern probably has a healthy back log of orders. This means games are selling and there is not enough reason to change how/when code is updated. Look at sales for GB and now BM 66.
Until code becomes enough of an issue to cut into profits then games will ship with incomplete code and updates will be sporadic. Good luck getting enough people to quit buying games due to code...... Stern has mastered the art of creating buzz with each release and creating the illusion that you need to "Buy Now" or you may not get it. And people are more than happy to get in line......
