New Version of Job Costing

I was wondering if anyone had heard anything in relation to the fact that Jobs and Job Costing was to be totally rewritten for Nav 5.0. What I would like to know is what features are to be added to improve on the old version of Jobs. Will this version be a true Job/Project management tool???

I believe this is just a rumour as we are hearing the same story since 2.0 !!!
