Probably this lens will land in my hands early this summer, but I am also considering the 50mm f/1,4D AF or the new 50mm f/1,4G AF-S, whats the benefit of purchasing a more expensive one like these? and do these two differ except for the focus speed?

The reason you want this new 50mm f/1.4G AF-S instead of the perfectly good 50mm f/1.4 AF-D that Nikon has been making unchanged since 1993 is that you can tweak manual focus simply by touching the ring. With the older AF-D lens, you have to move a switch on the camera to get between manual and auto focus.
Also bear in mind that the Nikon D40, D60, D5000 can only use AF-S lenses and not AF-D ones.
