The card in the bundle you linked to is a UHS Speed Class 1. The card in the bundle I linked to is a UHS Speed Class 3.
Page 11 of the G85 manual says you need a UHS Speed Class 3 card for MP4 4K. Page 30 says you need UHS Speed Class 3 for 4K photo.
For about $4 less than the $1199.99 "U1" bundle, you can get the $997.99 "U3" bundle plus a standalone $197.99 45-150 lens.
Again, hope this is helpful!
/u/Bro_Dave - for a grand, I would start with a brand new US-spec G85 with the 12-60 kit lens, a free 64GB card and a couple of extra batteries for $997.99 and worry about extra lenses later.
That said, if you're going to spend $1500 straight out of the gate, I would probably step up to an $1197.99 GH4 with V-LOG and a $297.04 used 12-60mm lens from Amazon Warehouse Deals.
No IBIS, but the V-LOG upgrade, 96fps slow motion and the headphone jack can be very useful to have. Plus, you'll have 10-bit output, if you ever want to record externally.
Here's the GH4 shooting 1080/96p slow motion:

Here is the more general image quality the camera can produce with graded V-LOG:

The GH4 also has 10-bit output via HDMI, and can record 10-bit 4:2:2 video like this to an external recorder (the G85 is limited to 8-bit 4:2:0 internally and externally):

It's a pretty good still camera too.
In my view, the GH4 is a lot more camera for a little more money.
Hope this is helpful and good luck finding the right camera for your needs!
