The information came up from source of Samsung’s Lebanon division and they discussed that on Facebook. According to that information, we can see the Samsung Galaxy S IV in action after May 2013.
So all those people using Galaxy S III, and they love being part of that model, will have to wait some more time now.
All that communication done between two people regarding any update can be seen in image below.
Afterwards, that Samsung Lebanon representative was asked for further information, he tried to avoid for further comments, but he didn’t totally rejected as well. He added that he gave that time because mostly the updates are released in that specific time period from Samsung, otherwise there is no confirmed date for S IV release.
