On the one hand: I can see the cause for upset. Most of the elements are there: sexualized characters, violence against same, misuse of religious imagery, gore, etc. It's basically a recipe for "how to upset people who are inclined to get upset about things that happen to fictional characters." The only thing it's missing is someone underage catching a bullet, too; if they'd had a twelve year old mini-nun holding the rocket launcher it would've been the perfect storm.
On the other hand: considering the above, it seems pretty well-made as cinematic game trailers go. The fight isn't completely one-sided (as is so often the case, with the pretty female puppets just there to get slapped down as so much fodder); the "nuns" lose, yes, but they certainly gave Hitman a few memorable shots on the way out. That over-the-arm disarming kick? Ow. So I don't see much space in there for a misogynistic angle - the gals aren't presented as incompetent* compared with their male opponent, he's just better. I dunno. It's obviously exploitative in nature as there is literally no other reason to have the nuns dressed that way for combat, and there is a definitive logic-fail in their tactical approach, but it doesn't seem like pure cheesecake. For all the fanservice approach to the visuals, it's a legitimately well-executed action scene.
I'd say the complaints are worth noting, but not "correct" in the sense that the trailer should be pulled.
*Okay, possible exception for the rocket-launching black nun. The others are all either a) killed by surprise before they can respond or b) outmatched in a straight fight where they perform reasonably well. That one exception contributes her rocket to the fight and...that's it. She wastes time posing over Hitman when he fell down instead of just freaking shooting him and pays for it, then kills one of her fellow nuns while she's being used as a shield and proceeds to drop her big gun (she really managed to empty the clip in just two bursts?) in favor of a slow-to-draw-while-lying-down pistol without even trying to present a moving target. She seems pretty terrible all around compared to the others.
