Heating is Not Drying

They are teasing us too much…
Should I read this as that their competitors only heat the filament, temporarily drying the filament while AMS HT will also block and seal the case to make it air tight to prevent the filament to regain humidity?
Should we read it as that the filament gets preheated before the print?
Will the AMS utilize the hot air from the preheated print chamber ?
So many questions…
