Samsung has stated on its (now pulled) Facebook page that an Ice Cream Sandwich update for the Galaxy Note, Galaxy Tab 8.9 and 10.1 will be coming hot on the heels of the Galaxy S II's Android 4.0 update on March 19th.
Galaxy S, Tab 7, and Galaxy W owners can also look forward to an update, albeit to Android 2.3 Gingerbread. Samsung has however listed Ice Cream Sandwich's Face Unlock feature under the upgrade feature list for the Galaxy S, suggesting that certain ICS features could be ported over.
We'll be sure to keep an eye out for more official dates from Sammy in the meantime, so stay tuned.
