For Photokina 2012, Arca-Swiss announces redesigned Z1g+ and Z2+ ballheads:
With the Monoball Zg1+ ARCA SWISS has improved the well known ballhead Z1g in all its aspects. The new head incorporates an additional panning top above the ball and its weight is reduced significantly. The Monoball Zg1+ guarantees a smooth, even movement and an accurate positioning of the camera. The MRGC (Motion Related Gravitiy Control), a variable and bi-directional drag is independently operative on both axis: with a horizontal movement the resulting friction remains constant, whereas with vertical movements the friction increases progressively. In all directions the movements are stabilized.
Improved as well, the bigger ballhead Monoball Z2+ is now equipped with a second panning top and additionally, its weight has been reduced considerably. The Z2+ combines the advantages of a ballhead with the features of a multiaxial tripod head. The secret hides in a newly designed ball unit which allows an individual and independent control of the x- and the y-axis, with gravity compensation and separate locks. The upper lever locks the smaller ball in the x-axis ( at 80°; 40°; -40°), whereas the lower lever is locking the bigger ball in the y-axis (at 140°; 90°; -50°).The Monoball Z2+ sports two panning mechanisms, one at the base of the head, the other, a proper panning top for panoramic photography, is located above the ball allowing perfect and leveled panorama stichings. Innovative and ready for all circumstances the ARCA SWISS monoball Z2+ is a clever synthesis of the advantageous ease of a ballhead and the exacting features of a three-way head.

Just announced: The Arca Swiss Mini L-Bracket (press release).
"The new mini L-bracket from Arca-Swiss complements the monoball®Fix lineup perfectly and is compatible with the current monoball®Fix quick releases"
Here is the Arca Swiss Product Brochure (1 MB PDF).
The new Arca Swiss D4/D4m Tripod Heads look really nice. The new "QuickSet" clamp design also looks like it could be a great improvement.
Arca-Swiss has joined Kirk, RRS and the others with the announcement of their Arca-Swiss L Bracket.
I would not call the press release "detailed", but the Arca-Swiss L Bracket appears to be a unique, universal L-bracket design utilizing the Arca-Swiss standard.
