At least in Israel anyway. Samsung Mobile Israel made a statement that they expect to roll out the update for unlocked and carrier-branded handsets in Israel starting March 15.
The announcement came from their official Facebook page and said:
We promised we were working on it. You waited patiently. And on 15 March it’ll arrive: Android version 4, ICS, to tens of thousands of GALAXY S II devices purchased from cellular companies in the country or directly from us. We are very excited for the launch, hope you are too
Whether other markets will see the same thing is still unclear. Hopefully the updates will roll out internationally around the same time.
