Leaked Galaxy S3 running Touchwiz 5.0 ICS?????

Don't know whether this is fake or not but this may be interesting video about Touchwiz 5.0 ICS. I found it on the Internet during the search of rumors about Samsung Galaxy SIII. What you guys think about it? Is it fake? Probably it was recorded recently. Calender widget is showing 12 Febuary.
