The board is legit, it IS for bitfury chips and I know the 55nm chips will have a similar packaging.
I am also a bit wondering how you can know that 11mmx11mm chips are similar than 7mmx7mm chips?
BFL, Bitfury. 49mm
2, 121mm
2. Heat dissipation? FUD! Don't sweat the details.

*The boards also have no voltage converters (to step down 12V to the voltage needed by the chips). Only Bitfury chips could be daisy-chained.
The cooling is also going to be pretty lulzy -- Bitfury chips are currently the best J/GH performers, and each chip hashes a small fraction of what Ken claims his 55nm chips will hash. Meaning more heat needs to be dissipated.
TL;DR: Ken doesn't understand shit, Bar is simply talking shit.
