I make this post becouse i have some thoughts about some next changes in tesla vehicles, model S, 3 and X.
There will be no bigger batteries in near future(1-2 years) becouse they optimize cells for higher charge rate, low cost and to keep the weight of battery or lower it.
I think they will keep the same capacity per volume or increase slightly(10-20%) but optimize for C rate and low cost. Depends on the capabilities they obtained for the new automotive 2170 cell wich should be different than 2170 used in V2 of powerwalls and powerpacks.
Maybe will launch 110-120 kwh battery for S and X when they will switch to 2170.
But the biggest question is if the switch will be when the model 3 will launch or somewhere in q4/2017 - q1/2018 ?
This depends mostly on the end of the 18650 contract with panasonic, availability of necesary 2170 cells and new battery packs with those 2170 cells.
They should switch to the new packs in the same time with model 3 launch, otherwise a lot of people will feel unsatisfied and will not buy S or X.
But this also depends when will be the switch to SC v3 and the new higher charge rate. Maybe those new bigger SC stations are prepared exactly for that.....
I see a very low probability to offer higher SC rate for model 3 and not for S and X in the same time.
I think this will bring cooled charging cable, cooled cables from charge port inside the car to the battery and cooling the battery also to sustain higher amperage and charge rate.
Most probably charging rate will be 400-500 kw, but maybe elon will jump to 1000 kw if 350 kw is a child toy

If SC will have cooling capacity as in one of their patents to cool the cables and battery in the car we can't know how far will they go and i don't know if higher voltage is necesary.
There is one more reason i think charging rate will be very high and some other thoughts, but in another post...it's late now for me and need to get some sleep
I may have some gramatical errors becouse english is not my natural language and these are just my opinions, don't take them as absolute facts.
