Dear Maysara,
You may have meant this as a joke, but it isn't funny. Please assume good faith, and remember there is absolutely no reason or motive for Wikimania 2010 organizers to withhold the videos out of spite.
As has been communicated in the past, the videos were never delivered by the company that performed the taping, and attempts are being made to secure the videos from them.
Perhaps the organizers can send an update if there's been any progress lately, but accusations such as the one you made are surely not helpful, and can easily offend.
