Go ahead and click on the video up top there! For me the preview image is still of the old trailer but the new one will play. The visuals of said trailer is credited to SkorpyoTFC who you can watch him give hilarious commentary on games here: Youtube.com
If you wish to watch the trailer on youtube you can do so at Cleril Calamity Studios official channel (not much happens there as of yet):
The game itself has not been changed in anyway. Only the trailer is caught up.
