Just a little more info---
The new board has different circuitry that does indeed solve the eye logic issues of the original BD5 board.
Here's the best part (I just recieved confirmation of this):
NPS will be offering a $20 trade in on the stock boards for the R15 board. That means you can either send your board in, pay them $39.95, and get the R15.....or......order the R15 for $59.95, send your board in, and get a $20 credit back when NPS recieves your old board.
