Mark has posted from Convergance about rumours that there will not be an FRX 7 release but it will be rolled into a new server offering. I have to beg to differ.
I am 99% certain that there will certainly be an FRx 7 release in the near future. I think the confusion is being caused by the positioning of FRx, Helmsman and PerformancePoint.
My understanding is that the FRx suite will be with us until 2012 at least and will be the out of the box tool for organisations for whom PerformancePoint would be overkill.
There are some more announcements over at Microsoft watch
