Many JJP games have been changed from original concept. Big deals? Yes, but the changes were needed and took place. Time spent worrying about any of them now is crying over spilt milk. No amount of tears will change them back to their previous glory. For instance ...
WOZ serial lighting either broke or left Owners worried it soon would. That was a poor design choice by JJP and was covered under warranty for many, yet others had to shell $800 out of pocket to buy an upgraded boardset.
TH switched from direct print cabinets to high res decals because of vendor issues. But the decals were beautifully done and buyers were offered a choice to switch to alternate Smaug edition with decals.
POTC removed 2 discs from playfield while adding three to the LCD (so technically you gain one while losing the wow factor). The moving trunk lid was cut too (a small deal). Both were poorly designed and had to be removed because they were unreliable.
DI is the single game that didn't receive a major adjustment of some sort. The original poor title and theming choice were never corrected, even after public outcry and suggestions were offered. Ironically, JJP took no action in that instance and it has negatively impacted DI sales.
So yeah, changes happen and we should always remember them, but as POTC stands - it is looking pretty good. The single biggest complaint is a steep price tag and complaints about that fell on deaf ears to. Ha, you want something more? Here's your big price increase ... BAM!
