An all new trailer for Mario & Sonic at the London 2012 Olympic Games has emerged showing plenty of characters and events.

An all new trailer has emerged from Gamescom showing Sonic and Mario once again square up for the olympics - This time taking place on our very own turf.

The trailer shows a huge roster of Mario and Sonic celebrities, plenty of iconic London places and of course, buses. Heck, Luigi even gets to ride an all too realistic horse, don't take my word for it though, watch the trailer below.

Mario & Sonic at the London 2012 Olympic Games is set for release on November 15th on Wii and February 2012 on 3DS.

What do you make of the trailer? SEGA have yet to confirm whether the final game will include rioting Goomba's.
