So here is my opinion and I have more questions than answers from what we've seen yesterday
It looks like a good, typical Volkswagen Facelift; it could've been much worse in terms of overall changes (I still have a hard time to differ old T-Roc and the new one

)
GTI front end looks like it should've looked from the beginning in 2019

By contrast, the photos shown show no difference at the rear end except for the taillights, which look great (and the question here - is how the rear turning indicator will work? is it going to be bicolored? From the shown videos, it's hard to tell. However, I can't see the separate indicator for the turning signal).
It would be great to see some changes for the rear diffuser (like we saw in the new Clubsport). I mean, I have nothing against the current one, but that's the facelift, right?
I don't understand the critics of the badge on the door. Such a badge was shown on a Touareg almost a year ago, and everyone is so surprised only now

I find it not bad at all; looks like a new design, at least. And it will be easy to identify FL model when you stand from the side. Looks more minimalistic and new.
New lighting emblem - it looks like a rear emblem for the FL Touareg but transferred to the front. It looks much more decent than the current one in the ID models (it looks cheap over there). I can't say it's something super cool at the front, but I have to see it in person. The one on Touareg at the rear looks so crisp.. but in red
I LOVE that they added gloss black to the buttons on the steering wheel. At least now it looks like the current one with touches, whether the previous one with buttons looked ugly being all-grey...
We talked a lot about the new display. The more I look at it, the more I find it okay. At least now, there is an option to open both maps and music player in one window in CarPlay

of course, we had that option before, but that was a hard time to do as windows were too small.
I love the power increase in the GTI. Can it do 5.9, 0-100 officially?

Waiting for the official presentation next week, more photos & videos, more reviews, and of course information about improved chassis, handling, etc

More to come!
