GH5 could have 4K 60fps and 8K recording?

Mapcamera interviewed Mr.Tadokoro Yoshifumi from Panasonic. Asked about the features that could come in future cameras Mr.Yoshifumi said they are working on:

1) 4K 60fps recording
2) 8K recording

I guess the first feature will certainly make it into the GH5. But I am yet not sure if 8K will come that soon…
