Jason pointed out to me that I missed a little tidbit in the previous Jakarta Post interview with John Chen. In it Chen states that BlackBerry is planning on rolling out the subscription enterprise BBM (Aka eBBM) this month. Specifically he said that:
We [also] have a lot of products in the enterprise spaces coming out […].We are looking at releasing our new enterprise offer […]. We have now set up BlackBerry Messenger (BBM) for enterprises called e-BBM, starting in June this year.
