The trackpad may not exist as you know it on the MacBooks out this year. Gestures will remain, but the ability to move the pointer using a finger may very well be non-existent. The pointer is inferior to touchscreen. Those who need to draw now use an iPad. Those who need to type and move though Documents need a Mac, but do they REALLY need a pointer? Gestures can do it all. Imagine the scroll gesture, but for everything. The pointer has had it's time.
