Mac OS X GM (4k78) ????

I have just recently gotten 4k78 havn't installed it yet but theres word going around that 4k78 is the GM does anyone know if this is true or not?
It is false.

4K78 is a FC (Final Candidate) release. But not the GM.
However, GM should be near the 4K78 release... With improvments, optimizations, and probably some uncle Jobs surprises...
