I bought the Region B Blu-Ray with the ASIN number B0010VXMRQ in May 2013.
I can confirm that IS the uncut version, complete with limb-chopping woodshed antics.
The picture is great considering the age of the film and the probable lack of care in looking after the master prints. The audio is okay but could have done with a bit more restoration work; in some places it lacks clarity, and a film with this many explosions ought to have the floorboards rattling a bit more often.
There aren't any extras unless you count trailers. But to be honest, I was happy just to be able to watch this classic Arnie-fest in HD. For added hilarity, get on the interwebs afterwards and watch "Commando: The Musical".
