I hope not.

I think it would be closer to "Watch when we get a consumer 6-core...it'll secretly be unlockable to an 8-core". AMD seems to like to keep its assembly lines to as little as possible so they get lazy with lasering and just disable cores. Maybe we'll see some of the glory days of Phenom II x4 unlocking again.

Disabling is faster and cheaper process, of course they will disable them. Plus, it sounds better to the masses "hey guys, i bought a quad core, but i actually unlocked 2 extra hidden cores!!!).

Gotta keep that value image somehow if they're going to jack up the prices to match Intel. :p

Anyone know what those 2 blue thing are under the CPU?

Please AMD... make a bang.
Please be competitive again with Intel

They are SATA ports for some reason.

I know we cant read too much into it just yet with the board being an ES basically, but anyone else notice those 2 SATA ports right between the CPU and GPU? Possible use for flash expansion to GPUs in the future?

No.

The SATA controller in in the CPU. Zen is a full SOC minus graphics for the 8-core. Quad will have an IGP.

There are also SATA ports in the normal spot from the CPU though. Only the black ones are likely to be from an add-on chipset. Same as any other MB we have had for years now. You dont see Intel boards with SATA ports right next to the CPU and GPU and they have had the storage controller built into the die for a while now.

There have been murmurings of Zen not dealing well with long motherboard traces for its high speed I/O. (SATA/USB 3.1/etc)

All motherboards have problems with USB3.1 trace length. That's the nature of high speed signalling.
