I think Pete is right. Jack from JJP would have ALOT of features and cool stuff hidden away to surprise the hell out of everyone.

That code on the demo model may have just been loaded to test switches etc only and maybe just for LED lighting etc. Its like when my AC/DC PRO first came with the basic code. The game was GOOD. But after uploading the next gamecode updates, which had literally hundreds of updates within it, it made the game GREAT. And the updates since have been better and better again over the 8 week period. The updates have stopped now and the game is bloody fantastic. Code can make a HUGE difference. It did on the PRO. Espescially dot matric and audio. BIG positive changes. The same will happen with WOZ after customer feedback as usual.

Its still very early days. ALOT can happen in a 60 or 90 day period. And even after the game is shipped, the code updates will happen and make any loose ends Terriffic. I reckon JJP will pull some rabbits out of hats and I reckon it will still be a EXCELLENT package.
I cant see JJP releasing anything but a very decent machine. We will all know by Xmas.
