I wish there was more talk about the chassis and what/how it's improved over the previous. Stiffer unibody as usual, dual pinion steering rack, body mounted sway bar. That's all I've heard. More context probably needs to wait for the full reviews beyond press drive.
Doug Demuro did a good job on pressing past the BS with the Subaru peeps on why they done what they done:
TL;DW I learned watching all the reviews out:
The "not Impreza" status of this WRX as a model allowed Subaru to give it more unique styling. Focus groups indicated they wanted "bold" styling, Subaru thought the fender thingers was a way to do that. Subaru PR guy says every new generation WRX is panned, people will get over it, grow to like it. I disagree but only time will tell on that one. It's not like they're always right, they missed the mark on that roly poly bar of soap '08 WRX.
Subaru says competition (e.g. GTI) sells majority automatic so they see an opportunity to increase sales overall with the "SPT"/CVT GT model. I guess that is alright, does smack a little bit of "those manual drivers will take whatever we give them". Maybe the exclusiveness of the GT and it's features is meant to be short lived to create some interest, force press reviews of the SPT, avoid the "we prefer the manual" comparisons on launch. Then they open it up later after all the buzz has been controlled.
Competition didn't demand an increase in HP so that was not a goal. They did hint at the tunability of the 2.4 being of interest.
The adaptive suspension is primarily for increased comfort, they indicated the normal WRX is equivalent to the "sport" setting on the GT, and it goes softer from there down to normal and comfort settings.
