Is there any anticipated release date for Helix (Zimbra 6.0)? I'm not expecting a definitive date because that is almost impossible to give, but something like "First half of 2009" would be sufficient. Only reason I ask is the CEO of the company I work for would like to know because of the slated syncing of shared calendars with Zimbra Mobile. So its merely for informational purposes. Anyone got any sort of clue? Thanks!
