I sort of answered my own question. I want to get the standard iMac so I can take delivery today which means getting a 1TB fusion drive. I was curious about upgrading the regular hard drive part of the fusion drive.
I'm not so bright so I didn't understand what PCIe was but now I see it is just a card. The Retina SSD is PCIe based....meaning, if you want to upgrade the SSD part of the fusion drive, you simply buy a larger PCIeSSD card. Google Mercury Accelsior E2
You can also upgrade the old HD part of the equation.
But here's the thing. There's something even better. You can throw these PCIe based SSD cards into an external enclosure and access then through the Thunderbolt port. That will give you the best possible performance..better than upgrading to Apple's SSD.
So the short answer is if you are in a hurry and want a new iMac retina 5K, go ahead an buy one knowing you can not only upgrade the internal SSD and HD but also access an EVEN FASTER storage solution via the Thunderbolt port.
A lot of people like me want to buy a standard config model from the store and then upgrade the RAM and Storage ourselves. This teardown story claims this can be done. But I wonder if more information about the storage can be provided.
The fusion drive looks like a regular hard drive with something plugged into the motherboard. What happens if we replace the regular drive with SSD. Does the Fusion SSD still operate independently, meaning more overall SSD storage? Is anything software related impacted?
