You're correct that both the 6708 and 6716 do not come with / cannot use 
a CFC, but they differ w.r.t. DFC4 upgradeability:

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/hardware/Config_Notes/OL_24918.html

"""
WS-X6716-10GE

DFC3A, DFC3B, DFC3BXL, DFC3C, or DFC3XL

Upgradeable? Yes. With either a WS-F6K-DFC4-E or a WS-F6K-DFC4-EXL

This matches what Cisco told me in a very specific response to a very 
explicit question; the 6716 is upgradeable, the 6708 is not. Note it's a 
DFC4-E, which is different to the rest of the 67xx cards, which take a 
DFC4-A. I assume this is form-factor related.
