Sony Japan Unveils the a7II Mirrorless Camera, 70-300mm G SSM II A-Mount Lens | explora (http://www.bhphotovideo.com/explora/photography/news/just-announced-sony-a7-mark-ii-mirrorless-camera?cm_mmc=EML-_-Holiday2014-03-_-141120-_-Body_Explora_SonyA7II-ReadMoreBttn)

Main new feature is 5-axis in-body image stabilization ("Shooters can now enjoy up to 4.5 stops of image stabilization when using any of their lenses, including adapted and fully manual lenses.") and it gains XAVC video and S-Log2 recording that the a7S has. The grip is also said to be a little larger.

Would a "II" version of the a7s follow, do you suppose?

I would bet £100 Richard that they will. The A7S is already popular amongst video users, so it only makes sense for business purposes at aleast.

$1700 body only. At least it's at the same release price as the A7.
