Sonic Rivals trailer

Sonic has been cursed with some pretty mediocre gameplay in the past generation when placed in the third dimension. But, the 2D platformers found on the Game Boy Advance were all very solid. Sonic Rivals, the upcoming PSP-exclusive title features 2D gameplay, but with 3D graphics.... So, will it fall into the same curse that all the other 3D Sonics have?

This trailer shows off some solid (and very speedy) graphics, but the gameplay worries me. Does it seem a bit too shallow? I'm afraid that because of its focus on racing, it might forget the important platforming element so crucial to a platform game. You watch the trailer and you be the judge.
