Look, I am not exactly a BFL cheerleader, but if the SC is an Altera HardCopy then the PCBs will be the same. Well, technically BFL will have no reason to change the PCB design -- I guess they could change it for fun if they wanted to.
However, the heat pipe doesn't make sense. They shouldn't need anything remotely close to that if they deliver on the power claims they've made.
If it's a HardCopy it really won't be a SC Single, since the performance won't even be in the same league as the 40GH/s they're advertising. Getting 3.5GH/s out of a bus powered coffee warmer would be a pipe dream.

If you are right that BFL is a scam, you will make money
BFL has claimed the SC products will use the same or less power than the current equivalent FPGA product. If memory serve the power draw of the MR is under 1200W, so 1TH/s@1200W would be 833MH/J. I'd hardly consider a bet claiming BFL will reach at least 42% of the power efficiency they promised in the first products some time between now and July 2013 to be BFL delivering. It's actually worse than that since the bet states they'll use the DC power input, not the power at the wall. The Minirig SC could draw 3kW at the wall and still satisfy that bet.
