I'll give a brief overview of the more interesting categories including which watches are included. All info is taken from http://bloom.bg/1Q5u5a5, where you can also find an overview of every section, while I only cover some of them.
Above is the artistic crafts featuring the:
Blancpain — Villeret, Cadran Shakudo (top left)
Girard-Perregaux — The Chambers of Wonders - The New World (top middle)
Harry Winston — Premier Precious Butterfly Automatic 36mm (top right)
Hermès — Slim d'Hermès Koma Kurabé (bottom left)
Piaget — Altiplano Scrimshaw (middle)
Romain Gauthier — Logical One Secret Kakau Höfke (right)
I can't comment on which watch might win, given that I have absolutely no expertise in the area of "artistic" watches.
More appealing to me is the calendar division, which requires some sort of mechanical prowess, unlike the artistic, which focuses more on how appealing the watch is. In the case of the artistic watches, however, I find most of them to be hideous. The calendar watches look better. I would have to venture a wager and agree with Mr. Pulvirent (author of the article on Bloomberg) and say the Nardin will be taking this category.

Tiffany & Co — CT60 Annual Calendar (middle)
Ulysse Nardin — FreakLab (right)
The chronograph category is arguably my favorite, featuring a number of very attractive offerings from companies including AP, Tag, Piaget, Longines, et al. My favorite watch in the batch is the tag, with vintage styling that I find particularly attractive. While I don't like how either look, I think the the Montblanc or AP will take this award.

Piaget — Altiplano Chrono (middle)
TAG Heuer — Carrera Calibre 18 Chronograph (left)
This would far and away be my favorite category (Mechanical Exception) if most of the watches weren't butt-ugly. This year, however, I am seeing far more attractive offerings. In particular, the Christophe Claret, Emmanuel, and Jaquet. While I am the first to admit that I don't know much about some of these watches such as the Dewitt, from what I know, I'd wager a guess to say either the Emmanuel Bouchet (which is also my favorite design-wise) or the Hautlence will take the cake.

Hautlence — Vortex (bottom left)

Finally we finish up the post with the tourbillon watches. When I think of a tourbillon, I typically think of a classic watch with vintage styling. However, about half of these are designed for the buyer looking for a contemporary design. It's sure to be a tight competition with companies such as Greubel Forsey, MB&F, and Ulysse Nardin in the mix, however I would wager a guess that Forsey's will just beat out the others.
