Sony will launch a new A7III, 135mm and 400mm FE lens this year!

We can be pretty certain this is what Sony is going to announce this year:

1. Sony A7III
   – 24MP Sensor (not the same as the A9).
   – same A9 autofocus system without the 20fps rate
   – to be launched in October-November
2. Sony 135mm f/1.8 FE lens
   -to be launched this summer
3. Sony 400mm FE (aperture unclear)
   -to be launched this summer

It seems like the heavy stuff like the A7rIII and A7sIII will be announced or ship in 2018 only
