Who knows. Maybe Chuck (Nucore) can get his system up and running and team up with Gene from IPB and reproduce Wizard Blocks.
I doubt anyone besides the current Williams IP rights holders can just come along and start making P2K games without buying or licensing the rights themselves. That would cost big bucks and would probably mean one of the current rights holders will have to give up their rights in the process.
With the current economic climate, I don't know if it makes much sense to embark on a brand new venture to make new P2K games. That combined with the fact that the popularity of pinball is in decline amongst the general population means it may not succeed. A big risk I would have thought.
