Leaf Intelligent Mobility facelift at CES 2017

I Can't wait to see what the Next Generation Nissan Leaf 2018 would looks like ...
Perhaps it may look like this Nissan Intelligent Mobility demo shown at CES 2017 this month.

I plan to buy a brand new Nissan Leaf 2017 on october/november this year,
I heard that the next generation of Nissan Leaf may become available "in a near future"
so it could end by a dilemma between 2017/2018 model for me ...

In case this "facelift" demo version may become available on 2018 model,
what do you think of those "sportier" front and rear bumpers ?

There's also a different "sportier" front bumper shown in this video:

Do you think those "sportier" bumpers enhance drag efficiency significantly on highway ?
It may result on a better autonomy on highway ...
I'm asking because I plan to drive on highway most of the time !

Thank you !
