New Lancia Delta HPE Concept pictures: Official or Photoshop?

The past few days I've seen a couple of hypothetically official, sketches of Lancia's Delta HPE Concept that'll be unveiled at the Paris International Motor Show this month. The later seem to have originated from an Italian site called "Autoinsight" (the last pair of photos).

Now, we've got another two "official" sketches of the Delta HPE Concept running around loose on the net (above photos). Besides having some differences in terms of front and rear end design, the two "official" sketches are very alike.

I'm not sure if either ones are official sketches or not -although both could very well be early stage designs, but if I had to pick one that I liked the most, I think I'd i preffer the first ones. I must add though that in my opinion, the rear end design in both sketches is a very big "no-no"...
