That's true!!! The images from the first 2012 sets are running out there, via the Polish LEGO Dealers catalog.
As you know I can't post them here, otherwise some TLG friends would become very angry... but I'm sure you will find your own way to peek them.
They confirm all the references here previously disclosed.
Hence let's proceed to the first impressions, by size order.
9390 - Mini Tow Truck
The smallest set with less functionality, of course. Front axis steering via HoG (the first of its size) and the winch goes up an down via the small gear on the side.
It looks like a mini-MOG.
9391 - Tracked Crane
Liked this one!
Superstructure rotation (guess there is no turntable in use). Boom with raise and telescopic functions, and winch goes also up and down.
9392 - Quad Bike
Buggies and Quad Bikes seem to be a recurrent inspiration, for the LEGO Technic theme, in sequential order of appearance.
It looks to have just three shock absorbers, as usual. And the chain is a nice detail.
Can't be sure but the panels and some parts, looks orange which would be great if confirmed. Could mean that the orange came to stay.
9394 - Jet Plane
Awesome! Reminds me a recent MOC from a French builder.
Variable wing geometry and retractile front/rear gear trains. One of these functions seems controlled from a gear on the back side (like if it were the turbine), if not both simultaneously.
Red! All red... It looks that suddenly (since two years) all LEGO Technic flying machines became red.
9395 - Pick-Up Tow Truck
American style Truck.
Not much to say... Steering via HoG; Opening doors; Moving tow fork in two movements, perhaps combined.
Black! All black... Maybe this time we got the 44's in the proper color!?... (TLG seems listening to us, again)
According to some fast translation I was given, from the notes in the catalog:
It seems also that none of these to be motorized or included any other PF element (thus the mention to reasonable prices, perhaps...).
