I think I only see 4 USBs (under the Firewires) in the
pic, those under the RJ45s look different, something like
eSATAs would look like.
And one of the slides says:
7. Features SATA 3Gb/s with Quad eSATA 2 interface Don't see any eSATAs in there - except those in the I/O backpanel. Maybe some hardware-illiterate techie-wannabe from Gigabyte marketing dept. can't tell the difference between USB and eSATA?
I suspect Gigabyte's incompetence in making the slides is the explanation.
edit:
Here's another preview of X38-DQ6.
That's not the same board though. See the attachments.
