I've been saying for a while that what the game needs is some story progression.
New girls are fine, but we have enough at this point to justify focusing on story for a bit. It doesn't need to be anything drastic, basically something that shows the impact of Lex's scheme. If the dev is bored, it could even simply be additional dialogue in the cells that demonstrates developments in the outside world (based on the girls' new reactions). It would also be super cool for some low level character like Det. Bullock to actually find out the truth. An event would be too much to hope for I guess.
Anyway, doubt anything will happen beyond adding more and more ladies so I digress...
