Those are such little things, though.
Swier. obviously played up the soldier angle of Cable. One, it's basically the entire premise - no longer is Cable playing mutant messiah, he's fallen back to his original role as a soldier, his entire "assignment" being to protect the baby. The soldier angle and all his combat training is right there when he confronts the ruffians, and following on that note, he probably wouldn't have changed the baby had he the idea that any were still in the area. If he was able to figure out where those three were, I'm sure he could have decided whether there were more or not. As it were, there weren't. No harm, no foul.
The baby on his chest is better than on his back. What else? Sitting atop his head? Hanging from a leg? Stuck in a book satchel that he can swing around and hit people with? There are only so many viable alternatives. Should he wheel around a baby stroller? Or hook the baby up to one of those elastic wristbands and teach her to walk and keep up? At least, on his chest, he can use his arm to defend her - the way he did when Deathstrike attacked, the way he did in the first issue. This is something he couldn't do in other scenarios.
As for going into the bar and getting surprise-attacked, well, it's just that - surprise-attacked. Would you have written a Cable who was honestly expecting Bishop? Were I Cable, I wouldn't expect Bishop to be there. I wouldn't even suspect Bishop to be there. I'd expect Bishop to be at the bottom of Predator X's poop pile. Cable saw Bishop get attacked and ran. By the time Bishop resurfaced, Cable was gone. And even then, Bishop, during his time with the X-Men, hasn't had a real penchant for time travel.
And it's like I said with Messiah Complex. Cable was acting off of something that gave him insight into what was happening, and it was clear that Bishop was, too, in that he was able to surprise Cable.
Heroes can't handle everything; else, it's boring. The Cable we have here has nothing but his training as a soldier - he has no TK, no TP, and now he has an antagonist who's going to be super thorn in his side. And Cable's stuck in a game of defense, for the most part, assuming. That's what's going to make this title good.
The art's another matter. Personally, I like Olivetti's fit. The panel work is good, it's fluid and static at the same time. It's simple, unlike Bachalo. It's painted but not an eyesore the way Alex Ross's stuff comes off as sometimes. I like the way it fits. But that's an utter matter of opinion.
