Sigma has come through and announced 3 lenses for PMA. I like the direction here from Sigma. It looks like 2 entry level lenses with OS and a constant aperture ultra wide angle.
Sigma 10-20 f/3.5 EX DC HSM
Sigma has announced an ultra-wide angle zoom, the 10-20mm F3.5 EX DC HSM. This new design squeezes a relatively fast F3.5 constant maximum aperture into a body about 10% larger in each dimension than the company's popular 10-20mm F4-5.6 EX DC HSM. The lens has a minimum focus distance of 24 cm (9.4 inches) throughout the zoom range, and features two Super-Low Dispersion glass and two Extraordinary-Low Dispersion glass elements for the correction of chromatic aberrations. It is designed for cameras with APS-C/DX sensors, and will be available in mounts for Sigma, Canon, Nikon, Sony and Pentax DSLRs.
Sigma 18-50 f/2.8-4.5 DC OS HSM
Sigma has unveiled a new large aperture image-stabilized standard zoom, in the shape of the 18-50mm F2.8-4.5 DC OS HSM. This lens features a new Optical Stabilization unit which Sigma claims will work on Sony and Pentax bodies with in-body stabilization systems. It also boasts a larger maximum aperture than the kit zooms typically supplied with most DSLRs, and incorporates Sigma's Hypersonic motor for fast silent autofocus. Designed for DSLRs with APS-C/DX sized image sensors, it will be available in Sigma, Canon, Nikon, Sony and Pentax mounts.
Sigma 50-200 f/4-5.6 DC OS HSM
Sigma has released an image-stabilized version of its budget telezoom lens, the 50-200mm F4-5.6 DC OS HSM. ThisÃ‚Â features the same new optical stabilization unit as seen on the 18-50mm F2.8-4.5 EX DC HSM also announced today, which is compatible with Pentax and Sony bodies with in-body anti-shake systems. The new lens also includes a number of user-friendly features rarely seen at this level, including aÃ‚Â hypersonic motor for fast, silent autofocus, and an internal-focusing design with a non-rotating frontÃ‚Â element. It will be available in mounts for Sigma, Canon, Nikon, Sony and Pentax DSLRs, and is designed for cameras with APS-C/DX sized sensors only.

I really DON’T get it.
The focusing rings are all going in the Canon direction, but…
The zoom rings all go the wrong way compared to Canon OEM lenses. Would it really be that much more expensive to make them both work the “right” way for each mount?
The same for Tamron, Tokina, Cosina and all the rest… :-(((((
