Looks very interesting. Maybe this will be the future of ETL tools, or maybe this will become part of PowerPivot to improve the ETL capabilities which at the moment are pretty limited. for the moment is it effectively a cloud based ETL or data exploration tool.
According to the site it is due for release in November, 2011
