I read on The Verge that they said it's coming at some point[0]. Not much but it seems like it would be far more useful on Android with more OS access.
Tasker is spectacular. I started with a simple thing to pause my music and read out any texts I get if I've got my headphones in. My favourite is one that turns my phone to silent after a certain time, and if someone calls then automatically hang up and send a message to them saying it's late and I'll call them back.
I've recently added the voice plugin, I need to play around with that more.
