how often Family pack driver updated

Hi,

  I have been using Individual model driver pack. Its takes lots of space and doens't make sense to duplicate the same driver which already exist in different model in sccm 2007 for osd deployment.

I would liek to use Family pack driver. just a question, if individual model driver updated, how often driver update in family pack?

For example: e6440 updated on 7/31/2014, does dell update same timeframe for family pack driver?

thanks orion
