Looks great and the larger board as was said, is simplified a bit. It said power was two 6-pin connectors so whether that's meant for an ATX PSU only or adapts to a power brick or something should be made clear soon enough.
I'm sure they'll use a power brick, with a mini-fit jr adapter. Something like this, but bigger:
