Although Apple has not announced the next new version but it is expected that new updated version of Apple Lojic Pro will be launched sometimes in the year 2012.
It is expected that the next Apple's retail update to the professional audio editing software keeps everything we know and love about it.
The next update will most probably will refine and streamline the UI and some features such as WaveBurner which is the main component of Logic Pro.
With those updates, we believe that the next version will be more powerful.
Looking forward for the Apple Logic Pro X in 2012
