The reason the Product Showcase forum display what most people have posted, primarily we post the items when we submit them to renderosity to approve (which can take a week or more at times). Posting a concept or "what were working" on isnt always a good idea, primarily because alot of developers are secretive about what their working on until their finished, this is for various reasons. In my case its because if the idea doesn't meet up to a minimal standard of what I planned , it often times gets scrapped. Then you can end up flooded with emails saying "hey when is your gizmoagadget coming out"
