As far as I know it's just nudity, no sex or anything. I don't know what's classified as softcore, so if it's that disregard my post xD Also it's probably a good publicity for them, supporting lesbian characters and everything, I doubt they'd change their mind.
Edit: disregard the bit about no sex, there is sex, it seems that the genitals are obscured or something. Whatever the case is, we'll see when it comes out.
The good thing is that in the mangagamer blogpost, they said "Let's make 2016 yuri year" or something very similar, so here's hoping they'll pick up more yuri titles :]
