It's extremely likely that they won't actually use "Over here" and "Anytime" at all in the film, if Robert Rodriguez is as competent as I remember him. Those samples were from Mac used by the first predator who, as we all remember fondly, was crushed by one of Dutch's traps. And exploded.
These predators wouldn't have the audio samples, and it wouldn't make sense for them to try to lure their prey with an unfamiliar voice.
The most likely case is that most of the sounds and music cues we hear are placeholders, as you'll undoubtedly recognize the same exact predator roar and the Alan Silvestri drum cues hear and there. This is actually pretty common for sneak peeks and things like this, to have temporary sounds or such, and also common for marketing to use familiar elements to elicit feelings of nostalgia for fans.
