Well, Intel recently claimed that 10nm yields are "ahead of expectations for client and data-center products". And they have Ice Lake-SP/-X and Tiger Lake-U/-Y/-H/-S ready for mass production on 10nm+, so unless there are some surprises when scaling up the production, we should expect to see a wide range of products on 10nm+ in (late) 2020.
But this video though, "leak" is the wrong term here, this video are speculation and opinions, even claiming 14nm+++ just came out and that 14nm++++ is incoming, and the real threat to Intel is RISC-V, evidently he is clueless.
