Stumbled across this in a GAF thread. Seems Atlus handle the distribution of NISA and IFI games in the USA and as such we have release dates for Criminal Girls (03/02/15) and Hyperdevotion Noire (24/02/15):

It's going to be a barren few months after that though unless NISA announce a load of Vita games in their February press conference...
