I still think it's coming. Unfortunately, this tight lipped approach they've adopted is entirely the fault of the community so we can't really point the finger at them for not sharing more details. They tried that in the past and it failed spectacularly.

Luckily for me, I am just interested to see if it's something I can't live without when it finally lands. I'm not actively in the market for an upgrade at the moment so waiting isn't a big deal for me.
