The previously-delayed Sigma 120-300mm f/2.8 DG OS HSM lens has a newly listed ship date of May 15, 2013. It’s $3600, but it’s a constant f/2.8 throughout the zoom range. It is a beast of a lens. Hit the links below for more details.
These new lenses are priced the same as their predecessors and should be solid additions to mirrorless kits – particularly the NEX versions due to the limited selection of available lenses thus far. I own the 30mm in the older version in NEX mount and have been more than happy with the performance it delivered at the $199 price point.

Sigma’s new 30mm F1.4 DC HSM lens will be available later this month for $499. The new lens is designed for APS-C sensor DSLRs and will be offered in Canon, Nikon and Sigma mounts. Check it out at B&H Photo at the following links.
The new Sigma 120-300mm f/2.8 DG OS HSM lens is available for pre-order in Canon, Nikon and Sigma mounts now for $3,599. Expected ship date is March 16, 2013. Hit the links below to B&H for more details.
It also appears to be in stock in the Sony mount option here at Adorama. Note that the Sony version does not include Optical Stabilization due to the built-in stabilization in Sony Alpha cameras; however, Sigma still prices the Sony mount version at the same price of the other OS versions.
B&H has the Sigma 30mm f/1.4 EX DC HSM lens for $289 (reg. $439) after a $100 price drop and a $50 instant rebate in all mount options. (Note the “DC” moniker means that this is for APS-C crop sensor cameras only.)
