AFAIK, Those modelling contracts only cover promotion for 1 game at a time. In the case of Karima Adebibe, it ended up being promotion for both Legend and Anniversary, but Anniversary was a one-off budget production that was going in parallel with Underworld, so there was little sense in signing on someone new at the time.
In any case, that's neither here nor there. Lusting after women is something we're anyway destined to do as males, so that's an aside to the game itself. At the very least, in the video that Conay linked, you also briefly get to see two new screens from the Thailand level (right around 0:40-ish). Not necessarily the best ones IMO, but the ones I think have the most impact would hardly look very good in a low-res streamed video feed anyway.
