Just see what Sony Rumors reports:-
http://www.sonyalpharumors.com/sr5-hot-16-50mm-f2-8-ssm-to-be-announced-in-late-august-for-799/
It will come very probably as the rumour rating is the highest, according to them.
I think this is really a good news to Sonyians with cropped APS-C Sony cameras and in fact the focal range and the lens speed/maximum aperture is just ideal as a standard APS-C zoom. As compared to the Pentax DA*16-50/2.8 SDM, the Minolta SSM technology should be far more reliable as it has been proven, btw. Frankly, if the DA*16-50 SDM is not so infamous for dead SDM motors, I would have bought one long time ago, and ditto for the slow focusing speed of the SDM.
