If the 'Saver' rate for the Swiss Pass will no longer be offered in 2015, can I purchase the rate now & still use it within the next 6 months?

The Swiss Saver Pass (2 people travelling together) will be discontinued in 2015. If I buy it before the end of the year, will I be able to activate it within 6 months - in June, 2015?
