Is M5 supposed to be "all of that" over M4?  I didn't really think V5 was so much better than V4. (except for weightmapping, which you can get in either software now it seems)  I guess she was a little more realistic in size...but otherwise? There is a lot of hype about Genesis, but V5 is rarely raved about.

M4 seems already about the correct size, so what will M5 Genesis have so much better than M4 Genesis?

Oops, and for the op, remember its a matter of choice here.  You'll still need to purchase something.  M4 -> M4 Morphs++, M5 -> Genesis Evolution Body Morphs, Genesis Evolution Head Morphs, etc...
