NIS 2010 with Outlook 2010 x32

Now that office 2010 have been in the mainstream for a couple of months when will we have Norton Internet Security protection for Outlook? I know the beta version of NIS 2011 has it but it's a pain to keep updating to a new release by the old one expires. Since the technology is tested and proven I don't understand why it hasn't been made available to general users.
