Both would be welcome.
I could have sworn I read someone on here say that the 4:2:2 10-bit in-camera will not be for the full 4k 60p. Must have dreamed it or read it elsewhere.
It's on the original Pana press release linked above.
Panasonic today announced that it has developed a new Digital Single Lens Mirrorless (DSLM) Camera LUMIX GH5 that is capable of recording smooth, high-precision 4K 60p/50p and faithful 4:2:2 10-bit 4K video*3 for the first time in the world*1.
*3 In 4K/30p, 25p, 24p, 23.98p video recording.
