I  was on the fence on getting the Ultimate Pack but have decided to only get the SkinGen Premium. 

Ultimate Pack Pro deal breakers for me.
I own the CC Essential Morphs & Skin, Headshot Morph 1000+, and Adjustment and Balance Morphs. I can't find a list of the additional 198 morphs to see it I need them. I also have accumulated a lot of Poser/Daz content over the years, so I can create characters in DAZ then transfer them to CC3+.
I want to make characters of all skin tones but the make-up and skin packs are mostly for light skin. I've been able to play around with the sample eye shadow that came with the 3.3 upgrade to look OK on darker skin, but if I have to do that I might as well make my own make-up or transfer skin details from DAZ content.
The new normal maps are great, but I own a lot of DAZ content and the DAZ Genesis 7 and 8 base character maps seem to transfer well. See Darius 7 transfer image below.
The Human Anatomy Set looks like presets for content in the other three content packs. 

So my opinion. The Ultimate Pack Pro is a great bargain for those who have not spent too much money on DAZ Gen 7 and 8 content, but Reallusion needs to add a larger variety of skin tones in the skin pack.

Hi Miranda, do we have a ETA for 3.4 yet? 



 

Hi Chris, no, it's not firmed yet. :(
