No check on available disk space : http://bugs.archlinux.org/task/11639
It is more complicated than it sounds, the old check was problematic
so it was removed :

Estimating upgrade size is not easy either, it is not only "new size -
old size".
Maybe "new installed size - old installed size + new packaged size"
would be accurate enough.
But this is meaningless on a partitioned system.
Also it does not take eventual scriptlets which could create files
during install.

This was also requested here : http://bugs.archlinux.org/task/9710
As Nagy mentioned, one problem here is that file-conflicts check
require to first download all the packages.
