Samsung has finally made an official statement regarding its plans to upgrade current handsets to Ice Cream Sandwich (Android version 4.0), and the short list is indeed quite short:
Updates will start with the Galaxy S II and Note in Q1 2012, but that time frame likely applies to world versions of the phone, so those with American carrier-branded versions of the GSII will probably be waiting a little longer. The rest of the devices listed will "soon follow."
There are no mentions of any other possible candidates, so if your phone isn't listed, you can rest pretty well assured it won't be getting an upgrade to Android 4.0 from Samsung. This may be particularly saddening for owners of Samsung's DROID Charge and Stratosphere 4G LTE devices on Verizon, as well as those with the Samsung Infuse and Galaxy S 4G - none of which will be getting the Ice Cream Sandwich bump.
