You forgot the important part under the video.
The video is obviously a computer mock up and there is no sound.
Here's the missing info, missed from the person above:

Industry experts speculate that the cost of the 2017 model will be slightly higher than the $28,000 that was attached to its most recent ancestor. More than likely, the cost of the vehicle will begin at the base price of $33,000. Various insiders have attempted to contact the automotive giant in order to retrieve various details, but their requests have been left unanswered. Mazda is ceasing to release even the most minimal pieces of information regarding the 2017 replacement for the RX-8.
