With or soon after iPads inherit iPhone's 4K cameras. The "3" came a few months after that generation of iPad's inherited the prior generation of iPhone's 1080p cameras. I'm guessing, this Fall's iPads inherit the 4K cameras and an TV "now with 4K" rolls out with them or soon thereafter.
OR, if one tries to see a pattern in all launches, the time between models is about 2.5-4 years, so the "5" would hit in 2018-19.
