Ask HN: Is Intel Xeon Phi many-core processor vaporware?

I contacted all of the distributors listed on Intel website for Intel Xeon Phi 7210 processor, but no one has it in stock. They are also not expecting any shipments of the product.

Intel announced Phi many-core bootable processors with ship dates in June, but they seem to be total vaporware based on my search.

Has anyone else come across a Xeon Phi Knight's Landing IRL? Any suggestions on how to get one?
