Questions Regarding Renewing and Upgrading from 2010 to 2011

Hello,

 

I have 27 days left on 3 computers for my subscription to expire. When is 2011 expected to come out? Should I renew now? Or uninstall 2010 on my 3 pc's and install 2011. What is the price?Will I need to run the Norton removal tool? Can/should I delete the folder on my desktop that is called Norton Installation files? I'm running Win 7 on all 3 PC's. Thanks in advance.
