30% off the $1500 MSRP will give you $1000 addition to the body only price to make it a kt, or if you use the $350 number it would be $1150 adder.
6D kits would either be $3099 or $3249 - MSRP
5Dmk3 kits would either be $4499 or $4649 - MSRP
...and it would probably mean that the 6D + 24-105 will be a no-show, so the 6D + 24-105 @ 2899 will turn out to not be an option. It will probably be 6D + 24-70 f4 @ 3199 only.
... the Nikon D600 sells at BH with 24-85 today for 2596.95.
... I decided to defer my gear upgrade to the spring, so I have time to mull it over and look at reviews. I like my prosumer Canon L glass, but now it is clear that the "prosumer" lens types are moving into professional price brackets. That kind of defeats the whole marketing niche idea of prosumer glass.
Just another random thought: with Canon sending prices to the stratosphere, Nikon has a real opportunity to drop a FX sensor into a D5200 style body and sell it with the 24-85 for $1999. I'd like to get that rumor started right now.
