Quoted from Whysnow:
The reality is that the pinheck board is what Spooky has been using and from my experience with buying Proc boards and from what I know about pinheck board, one is far more expensive.
There is a lot more electronics involved in what Scott is doing that the heck board can support, so it is not just a one for one replacement. In addition, for a production run the board cost is going to be lower than retail given the economies of scale.
I seriously, seriously doubt Scott would even consider going forward with this if he needed to re-write all the code. TA was built on SkeletonGame/PyprocgameHD, which is thousands of lines of code, with major contributions from at least four different experienced developers, as well as plenty of others contributing smaller bits, all of which would need to be replaced as well and the majority of that code Scott has no deep experience with.
To even suggest this is just ludicrous.
