to the interview over at ATI-Forum.de, the 3DMark 11 Deep Sea tech demo seen over at Computex is just for show and won't be included with the final release of the new 3DMark 11.
According to Futuremark, this is the first time that Futuremark showed some content from a new benchmark before the launch, and it was simply used to demonstrate Directx 11 technologies and the 3DMark 11 engine. Unfortunately, Futuremark still keeps any info on the actual 3DMark 11 test under wraps.
Another interesting note is that the 3DMark 11 will be avaialble as a "free edition" as well and will offer unlimited runs, which is made possible due to advertising that now goes to MSI.
