I don't see how this is a big deal in older games you had to use certain faster characters to get the best time trials. So as much as I had more fun with toad for his recoverability and acceleration I needed to use a bowser or DK for top speed to get the best time trials. I don't see how this is much different.
The problem they have is not that some characters/vehicles are faster it is that appears to be the defining ability. They have equilized the recovery time too much or have at leat not made it long enough for the bikes.
Final* Word on Game Delays:
The game will not be any better or include more content then planned. Any commnets that say so are just PR hogwash to make you feel better for having to wait.
Delays are due to lack of proper resources, skill, or adequate planning by the developer.
Do be thankful that they have enough respect for you to delay the game and maintain its intended level of quality.
