One thing is very clear from spy shots, the car is lower and wider.. Thanks to TNGA..
As far as styling , Toyota keeping it more conventional sedan unlike Civic which took a completely new styling and that is Honda brand wise including Accord, more of sportsback type.
Side skirts , fenders arches and any character lines will make it how we see it. Wheel design as well.
Keep in mind the purpose of camouflage is that paparazzi photographer can't take the design clues.. Under wrap we might be missing any curves and lines..
