I am not quite sure about the long term ramifications of this but RIM announced some new dates for BlackBerry Jam Americas this year. BlackBerry Jam Americas will be part of the BlackBerry Live conference (Previously BlackBerry World) this year. I am not sure what that means for the regular BlackBerry Jam Americas in October time though RIM did have a BlackBerry 10 Jam event during last years BlackBerry World conference.
Either way you can find the details on BlackBerry Jam Americas here. It will be running from May 14-16, 2013 in Orlando, Florida right by BlackBerry Live.
