This is the rumour regarding Logic Pro Apps and MacBooks to see update at WWDC | 9 to 5 Mac The problems with that rumour is Apple have never announced pro apps at WWDC and it is highly unlikely that Apple would release Logic 9 before Snow Leopard. I am guessing that an announcement regarding Snow Leopard is likely but I doubt Logic 9, most people expect a major update to Logic 8 before Logic 9 is released. Even if Logic 9 is announced I wouldn't expect it to be out until early 2010. Another thing to consider if you are holding out is early adopters of Logic 8 complained that it was very buggy and are in no hurry to upgrade as they believe that Apple has finally got it right so now would be the best time to buy and then upgrade to Logic 9 express for $99 or studio for $199 once they sort the bugs out with it. The thing with technology is there is always something new coming out and if you wait for the new thing you never buy anything, the best time to buy is when you need it.
