Usually at VOI's the engineers, designers and marketing people are in attendance and gathering feedback from the attendees as to what they would like to see in future products.
They usually like to take advantage of the gathering to make any announcements that have been OK'd. Mopar will be on hand, and usually show all their latest goodies.
I would also expect to see any decisions make on racing the new Coupe to be made public there.
DC, as would be expected plays things close to their vest, and has been burned before by announcings things privately that show up within hours on these boards and the internet, so the days of them being previewed to us may be numbered.
At VCA Board and Presidents meetings officers take a pledge not to reveal any of the information gathered there. The Viper insiders feel a little more free to discuss items. Attendees in kind respect any embargoed information.
Needless to say, lots of activity is taking place to restore Viper to the dominate position for American sports cars.
I once asked a Viper engineer if he could let me in on some upcoming products.
He replied..."Can you keep a secret?".
I answered expectantly..."Sure I can".
He replied..."So can I".
