There's some advance information about what the minister is likely to concede: not much. See the stories in The Telegraph and Indian Express. But the Times of India is a little more blunt: "Sibal won't oblige [IIT] faculty." So there.
The only real concession is on the 10 percent floor on OCAPs; it is now likely to be called an "advisory" provision, and not a mandatory one.
The 40 percent cap on senior professorship, the IITs are going to be asked to go to the IIT Council when they hit that ceiling, and ask for more. That's autonomy for you.

“This meeting is in response to the IIT faculty’s telegram seeking an appointment with the minister. ...,” said a ministry official [source; Bold emphasis is not in the original].
