I've been following this thread for awhile, and until today I've been thinking we "deserve" an update. However, after stepping back and really thinking about this, I realize I've never even reached all the wizard modes. Therefore, why do I need an update? The cities were probably never intended to more than the minor call-outs you hear when starting a new song. The game has 5 multi-balls, which I would be surprised if many have actually reached without adjusting the default settings. And plenty of adjustments are there to make the game easier to progress through, if desired. Honestly, what "huge" code update do some of you envision? Maybe fix a couple bugs but even those are few and far between.
This thread is loud for sure, and likely making Stern think about how the game was developed, marketed, and enhanced. So why hasn't Stern released a code update within the past year for KISS? Well, GG pretty much said it - they don't see it worth the expense yet, simple. Does that hurt some peoples feelings, sure, but don't let that get in the way of playing and enjoying a "good" game.
Keep on flippin'
