it is frustrating that the date keeps getting pushed

hey Jack, distributors getting demo models is not a promise kept!!!!

I know your frustrated Pete but theres not a lot you can do about it except pull out if its pissing you off that much.
Now we know that the boards have to be redesigned it makes the past couple of months make sense..... software delays.
My guess is that they were trying to make the software suit the boards and eventually gave up and decided to go back to  square 1. Disappointing i know.. its a real bummer.
Id say this is the last thing Jack wanted.. and its going to be costly.
Bugs...bugs...bugs... all being ironed out.

Demo models are just that... demos. While it is a full machine, its not the full game and once the boards are finished these have to be swapped over ( was just a dongle removal).

I wouldnt worry about the date Pete, so long as the game is 100% when it arrives.
