Is it planned to use Launchpad for translations? Using po files are so hard to do synchronized translations working with many translators for each file.

That's why the coordinators exist. A good coordinator will scatter the work for the team so no one duplicates the work.
Launchpad might be good for new users that don't want to work with SVN, but it's slow and it often timeouts. Lokalize is easier to use, because has autocomplete, suggestion fill/translation memory, glossary and synchronise features.
