Anybody here who might know anything about future FM development would also be under a non-disclosure agreement, so forum member's comments one way or the other would have to be taken with a grain of salt.
That said, though, there are relatively new blogs where Adobe product mgmt folks participate, e.g.: http://blogs.adobe.com/techcomm/ which to my mind is an encouraging indication that the FM world isn't shrinking quite as much as it might have been in the past few years.
