Yes, the Media Import module allows you – in contrast to the "normal" upload – to import files even bigger than 2GB.
Background:
Due to a PHP bug (https://bugs.php.net/bug.php?id=44522 and http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=685383) the form upload of files bigger than 2GB is not possible.
The Media Import module reads the files directly from the file system. Thus no limitations of the file size apply.
