An interview with Dan Slott is up on Comic Book Resources here:

There is a preview art page too. Sadly, Chris Bacchalo is doing the art and personally, I detest his art. It's manga-y and confusing, so I guess I won't be picking this one up.
This is what Slott says about Anti-Venom's story in Amazing Spider-Man: Extra #2.
"Hitting stores January 28 is Dan Slott's next contribution to the Spider-Man mythos, the previously mentioned “Amazing Spider-Man: Extra” #2. “It picks up Anti-Venom emotionally, spiritually, and physically where we left him in 'New Ways to Die,'” the writer said. “We get to see him in his new status quo and the first big bad he runs into is Mr. Negative who, little does he know, is the guy who made him. That's going to be a big thing for him. Will he find out that Mr. Negative is the cause of his transformation into Anti-Venom? You'll have to read it. One thing I am going to say though is that there's a status quo change that happens in this book and it's an important element in the world of Spider-Man.”
Slott's Anti-Venom story is a 22-page full length tale. “If Anti-Venom had his own comic, this would be a good first issue,” he said. “It sets things up for his future appearances. You get to see developments with Martin Li, Mr. Negative, Aunt May, and Anti-Venom. So it's all good.”
“It's all good” is also what Slott thinks when he looks at the artwork of his collaborator on the Anti-Venom story, Chris Bachalo. “The amazing thing about working with Chris Bachalo is that the work starts out gorgeous and every step of the way it's like 'Oh my god! That looks even better now that it's in ink! And now look at the color!’ Because there's all this stuff he does in layers. So you see it and you're happy and then you go from happy to ecstatic and then from ecstatic to drooling. So it's amazing working with Chris and seeing the whole thing come together.”
