There are some features that im looking forward to testing, especially the Lineage and Object Dependancy part of SSMS.

Of the New T-SQL commands THROW and the new addtions to the EXECUTE command look to be of interest, as im not sure I will ever use SEQUENCE as I cant figure out a use for it at the moment.

The Data Quality tool that MS are introducing that looks as though it may have promise, I just hope its a lot more friendly than the MDS offering in R2.

Then theres the change to the BI stack with the introduction of BiSM, I'm still not sure what its puropse is except to try and start unifying the BI front end under a single UDM.

PS : Has anyone heard when CTP2 is due for release as I've seen posts referencing it without a link to the download site.
