Even though SQL 2014 is by far not complete in CTP1 and more is to come, you should be ready for a new way of developing Datawarehouses - if In-Memory-OLTP is not enough "developer-stuff" for you.

Why is that?

Because it can be foreseen, that from that release on, ColumnStore will be the new standard storage-format for Facts as well as Dimensions - which is a big shift from anything before.

You can read some more on the reasons behind here: www.insidesql.org/blogs/andreaswolter/2013/06/sql-server-2014-columnstore-indexes-batch-mode-improvements
