I got them on the car now and since it's a new tire and I found no info, save from some Japanese site and one Norwegian review (Link) I though I'd start a tread for people who got the tire to tell everyone their experience.
So far for me:
Dry:
Pro: Much more quiet than the summer dunlops
Cons: Super soft (pro for when it's colder and there's snow and ice?). You can feel the tire blocks moving around when accelerating hard, might not be a problem for non-speed 3s. Stopping feels mushy. Turn in is also mushy and vague.
