switching from zaxs to nis 2010

i'm nearing the end of my za subscription, and i've decided to switch to nis.  i can buy a new nis 2010 license at amazon for ~$34, about what it would be to renew my za subscription.  question is, will the license key i get from amazon be good for nis 2011 when it's released?  posters at amazon say they get 366 days, but no one mentioned whether that would include an update, e.g. nis 2010 -> nis 2011.  thanks!  (8

 

afterthought:  i'm also thinking about using the nis 2011 beta for 60 days, but there's no guarantee i can get the same ~$34 deal.  any success/horror stories would be appreciated.
