Thankfully, DQS team has announced DQS Team blog, which would be a driving resource for the community looking forward to DQS. Expect more updates on SSDQS from me very soon.
After a few screens, you would find the glimpse of BISM. You would get options to select Multidimensional mode (OLAP and SSAS) or Tabular Mode (Powerpivot and VertiPaq Engine). This seems the realization of the vision of enabling users to choose OLAP or Tabular data and querying it with MDX or DAX, with any combinations.
After that you would get few other new pages.
