The ICC Test Predictor only goes till the NZ in SA series in Feb/Mar 2017. Still quite a few series till then. My best guess about the outcomes of these series is:
Pak - WI = 3-0
Bang - Eng = 0-1
Zimb - SL = 0-2
Aus - SA = 2-1
Ind - Eng = 3-1
NZ - Pak = 1-1
Aus - Pak = 2-0
NZ - Bang = 1-1
Ind - Bang = 1-0
NZ - SA = 1-1
If the above results occur, then the predictor says the rankings of the teams will be:

India will have a somewhat comfortable lead prior to hosting Australia in Feb/Mar for 4 Tests (which are too far out for the Predictor atm).
You can play with the Predictor to see how different scenarios pan out. If India draws with Eng 2-2, it will just be ahead of Australia with 114 points. If to this scenario you add Pakistan winning 2-0 in NZ, and matching Aus 1-1, then it would edge ahead of India to get back the #1 ranking.
I am of course hoping that India beats England 4-0 in which case it ratings would be 121 rather than 118. If it follows up with a 3-0 or a 4-0 victory over the visiting Aussies, then it's grip on the
#1 ranking will be firm for a few years.
