Quoted from arcadem:
With all of the speculation about WW being the next JJP pin, I decided to re-watch the Gene Wilder version of the movie to figure out what that pin might consist of. And, it hit me that it could be made rather easily as a re-skin of WOZ. Replace the Yellow Brick road with the Chocolate River and make the upper play fields versions of key elements of the factory and the elevator. Replace the haunted forest with oompa loompas, etc. Doing that would save money and time and make it feasible to do 2 titles in 2019. Oh hell, Pat Lawlor and Jack know better than me but, it's just a thought. Crazy, huh?
What do I know, but I don't see any way that they would do a re-skin of WOZ. They are about to release a Yellow Brick Road edition of WOZ, so they won't want to compete with themselves. Also, WOZs are still in production and selling. It's not like it is a 10-20 year old game that they would re-skin. And, a decent chunk of their consumer base already has owned or currently owns a WOZ, so they would likely lose most of them as customers.
I think Willy Wonka is a killer theme that deserves a brand new layout and brand new toys. I hope JJP does it and hits it out of the park. I will be in line to buy one!
