Spoiler: Sonic's speed gets nerfed. Again.

People who still play the Wii, here’s your chance to get in on some nice competitive action! The latest trailer for Mario & Sonic at the London 2012 Olympic Games has been released from the depths of SEGA PR and is now ready to be consumed by your eyeballs.

There’s some gameplay to be had, as well as mention of over 30 games to play. Also, horsies are involved for all you pony enthusiasts.

This’ll be out for the Wii on November 15th, so you still have plenty of time to buy fresh batteries for your Wiimotes.
