It may seem kind of silly to be looking ahead to 8K when the average person can barely watch 4K content, let alone record it, but a lot of industry experts seem to believe that 4K will be a smaller stepping stone on the way to 8K, which might stick around for a while. Technology moves so fast at this point, that future-proofing technology of any kind seems impossible. 1080p recording in DSLRs was a big deal for a while and now you can record it with a toy camera. The $500 GoPro records super clean 4K and now Panasonic has brought 4K to their mid-level ILC cameras. Who's going to make 8K first?
