Sometime after February 2015 could mean infinity. 
Last year people were saying that we'll switch to the new one in January. Now it's AFTER February. Somehow I feel in March we'll hear about Q2... well i believe theymos doing the best he could for the new forum , it could be june or july, but im pretty sure it will be in 2015
Theymos is not the developper of the new forum software , he hired other developpers and the budget is one million dollar . and No it won't be that late , Yes on 2015 but not that late . the Beta release will be very very soon probably this month , then the Final release shouldn't take long after the Beta since the Beta is only to find bugs and exploits etc ... so yeah .
