Once again we have two different models each for the iPhone 7 and iPhone 7 Plus.
Model A1660 (iPhone 7)
Model A1661 (iPhone 7 Plus)
FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 27, 28, 29, 30)
TD-LTE (Bands 38, 39, 40, 41)
TD-SCDMA 1900 (F), 2000 (A)
CDMA EV-DO Rev. A (800, 1900, 2100 MHz)
UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
GSM/EDGE (850, 900, 1800, 1900 MHz)
Model A1778 (iPhone 7)
Model A1784 (iPhone 7 Plus)
FDD-LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 18, 19, 20, 25, 26, 27, 28, 29, 30)
TD-LTE (Bands 38, 39, 40, 41)
UMTS/HSPA+/DC-HSDPA (850, 900, 1700/2100, 1900, 2100 MHz)
GSM/EDGE (850, 900, 1800, 1900 MHz)
Models A1778 and A1784 do not support CDMA networks, such as those used by Verizon and Sprint.

It appears the biggest difference is the A1660 and A1661 include TD-SCDMA and CDMA bands. The former being a Chinese 3G standard and the latter being mostly used by Verizon and Sprint in the US. It appears these models will be the true world phone versions of them and that the A1778 and A1784 will likely be sold by AT&T and T-Mobile in the states.
The SIM-free models are typically not available on launch, however the iPhone SE changed that. I'm hoping for a SIM-free version of the A1660 for myself at launch.
Any speculation welcome.
