Ricoh lease contract for the Pentax brand ends in 2020?

Well this is a surprise:

A reliable source reported on Pentax Forum that the

‘Pentax ownership belongs to HOYA, the right to use belongs to Ricoh, and the lease contract expires in 2020. Maybe this is why Ricoh does not continue to develop Pentax.’

It would be a serious surprise if Ricoh couldn’t use the Pentax brand name from 2020 towards. I hope Ricoh will still manage to extend the terms of use!
