Hello,
The due date for Adaxes 2013.1 release is March 21 with a possible delay of one week.
As to deciding between Adaxes 2012.1 and 2013.1, approximately a month before the release we started to generate license files supported by both Adaxes 2012.1 and 2013.1. So, if you decide to purchase your license for Adaxes 2012.1 now, you will anyway be able to upgrade to Adaxes 2013.1 later, no matter whether you buy the Upgrade Protection feature or not. So, I just suggest that you purchase a license for Adaxes 2012.1, if it suits your needs, and when Adaxes 2013.1 will be available, you will have an option to upgrade for free.
