Sonic Colours announced

Sega have been trying to reinvent Sonic for what seems like an eternity and the next attempt from Sonic Team is called Sonic Colours. It's heading to Nintendo DS and Wii and will see Sonic collecting small coloured alien wisps as power ups in order to foil the latest evil plan hatched by Dr. Eggman.

Here is a full description of the plot... not that anyone has ever cared about the plot in a Sonic game. Just bring us speed, and lots of it:

"The diabolical Dr. Eggman has hatched another plan for world domination! He has built an amazing interstellar amusement park, floating in space around Sonic's home planet, bursting with incredible rides and attractions. However, all is not as it seems as Dr. Eggman has abducted an alien race called Wisps and is harnessing their colorful energy to fuel a sinister plot. However, before Dr. Eggman completes his evil plans, Sonic discovers his mysterious theme park in space. When he arrives, Sonic finds he is also able to use these alien powers and is ready to help! Sonic will need all his speed and skill as he faces this test, but, empowered by the alien energy, it's a test he'll pass with flying colors!"

Sonic Colours will be released this fall and will feature prominently at E3 next month.
