Mac OS X Boxes, more Speculation on GM
As various people have confirmed - OS X Retail does reflect build "4k78"
Theories that those pics of boxes/builds were from "preview" copies for retail shops seems to be countered by this pic of stacks of (the same) OS X boxes and these pictures of installation of OS X.
From the latter page: "I don't know what they did to speed it up but it truly flys now..."
So, real 4k78 or optimized 4k78... it's days away now... and it does come with Developer CD's. Now if only we could revive Yellow Box for Windows.
