500 Multimedia Controller - will this ever be available?

Does anyone know when will this actually launch? It's been almost half a year since this was announced, but I haven't seen anything otherwise about it.

Post says March 2017, but it's June now, still nothing on the Lenovo site. Looking at getting it to replace my crummy keyboard for my HTPC.
