You may have seen this already if you follow me on Twitter but I thought I'd leave it here - just in case you need to find it again. It's a great promotion of the game and I feel it should make a great advert for the game and Vita in general.
The video came in a package sent to certain press teams in Japan, along with an apple and the message "You will control gravity for the first time".
The game is due out on 9th February in Japan and believed to be released on the Playstation Vita launch date (22nd February) in Europe and US. Note that the European release is apparently PSN-only.
