Kolab 2.2 Release?

[Michael Pasdziernik]

Hello,
currently I'm planning to migrate a customer from scalix to kolab,
but I'm asking me if I should wait for 2.2 or install version 2.1 or 
perhaps install 2.2b2 and introducing the horde client to the users
when 2.2 is released. 
Is it possible to give a forecast about when kolab 2.2 going to be released, 
rather within weeks or within months?

Thank you and regards
Michael
