Just an FYI LabVIEW 2013 SP1 appears to be up on NI's site.
http://www.ni.com/download/labview-development-system-2013-sp1/4527/en/
I generally only stick with SP1 releases for products, so for me this is when I get to actually use all the new features in 2013 on real programs.
Another odd thing is the release date is in the future stating 3/10/14.
