The only way I want to see Bayliss return would be on a another make of motorcycle. Right now he's riding on the coat tails of Fogarty. I can win but its gotta be on a Ducati (with every advantage written into the rules).
And I like Bayliss. I think he's a real stand up dude, has real talent, is modest and humble. If he'd won titles on any other make i'd be even more inclined to be a bigger fan.
Toseland winning on the Honda may be a bigger deal than anyone realizes, because at the time he won, it (Honda) was not the best bike on the grid, nor the fastest.
Personally I'm in no hurry to see a Duc at the front anytime soon... Aprilia, BMW, and Yamaha are creating a great product and have been at it all of 2 years...
