I think LP9 64-bit for OSX-SL will be released in the near future via an update.
It makes absolutely no sense to keep LP9 as a 32-bit application. This would be completely out of line with all other competing DAWs, and OSX-SL focus of offering a 64-bit Kernel, and other performance boosting features (GCD, Open CL).
The fact that RMX 1.9 is now 64-bit should say a lot ! LP9-64-bit should not be too far away
