JohnCM,
A little history:
Mgmt received updated event counts from trial sites. Through mid-2012 they were expecting data around the end of the year.
After the last DMC safety review in Sept12, they changed the guidance for "in January."
DMC has access to more data than the company gets and obviously told them eoy was not feasible but if there were ANY chance of going much later, they would have just said "in 1Q13." Because they went with January, and recently reiterated that to several shareholders, I simply have to believe it happens In January.
