With all these fighters something tells me that those pregnancy test will coming in handy. Would be 100% amusing if somewhere along the line you could knock up some of the female fighters /pussy's put up. Image the how amusing it would be with this one. You finally beat Christian's ass in the ring and so says the rules the pussy he puts up (in this case Christian's mother) becomes yours. You fuck her brains out until she like all the others is a slave to your dick, then the cherry on top is while doing so he knocks her up.
While far-fetched I would laugh out loud at this one big time. But if not my guess is something with Annie is what the test has to do with since you can actually knock her up during the Jet mission.
As for waiting not to much longer seeing as in 5 more days it will be the 20th.
I really do hope the pregnancy tests come into play at one point or another. They've been in the game since the beginning and have had no use thus far so who knows when they'll finally be utilized. Though the scenario you present would be both hilarious and something I wouldn't actually mind happening.
Two things I hope for the most in this update is more Maria content and the opportunity to bang Christian's mom. The only thing I'm SLIGHTLY worried about would be that since this is the most (or implied to be) content heavy update in a while some characters will be getting more exposure and even some new ones might be introduced. I'd just be a bit irritated if Christian's mom, the Stealth Trainer girl, or that co-worker of Maria's were given content in 1.5 before anyone else like Mindy and Maggie's case was.
Of course, I'd also LOVE to get repeatable sex scenes with those girls (Christian's mom at the top of the list as far as newish characters go) but only after we've finally gotten the content for Shasha, Laura, Amy, Beth and the girls that have needed questline updates for some time.
