NIS 2011 & NIS 2012

Hi,

 

1. My NIS 2011 For Windows will be dued in November. And now NIS For 2012 is released. "Should I waite for the 2011 For Win due date  or purchase the NIS 2012  now?"?

 

2. I can purchase the NIS 2012 for Win lince for "3 Years", What should I do if the NIS 2013, or NIS 2014 is released during the 3 year period.

 

3. Will the NIS for Mac release with NIS for Win at the same time?

 

Thanks.
