I would love it to be an ongoing but I don't see it as that.

Ongoing as far as we know. It's definitely not a mini-series because the issues aren't numbered that way (no 1 (of 4), 2 (of 4), etc.) But with the concept of the book, and with Jim Lee on art, I have no doubt that it won't last long. Probably a limited series...

This is what the solicit for a DC miniseries looks like:

THE HUNTRESS #1
Written by PAUL LEVITZ
Art by MARCUS TO and JOHN DELL
Cover by GUILLEM MARCH
On sale OCTOBER 5 • 1 of 6, 32 pg, FC, $2.99 US • RATED T
Look out! By the end of this hot new miniseries, the Huntress will have the largest price on her head in DC Universe history.
What will the Huntress do that warrants such a death mark? And who puts it there? The jaw-dropping events will be revealed as the Huntress heads home to Italy and embarks on a mission that defines her life. Don’t miss out, because this story will tie in to upcoming events in BIRDS OF PREY!

This is the solicit for Superman Unchained:

SUPERMAN UNCHAINED #1
Written by SCOTT SNYDER
Art and cover by JIM LEE and SCOTT WILLIAMS
Backup story art by DUSTIN NGUYEN
1:300 B&W Variant cover by JIM LEE and SCOTT WILLIAMS
On sale JUNE 12 • 32 pg, FC, $4.99 US • RATED T
Combo pack edition: $5.99 US
When thirteen satellites fall from the sky in one day, the logical suspect is Lex Luthor—even though he’s still locked up in prison! But a stranger question remains: If Superman didn’t stop the last satellite from falling, who did? There’s a mystery hidden where even Superman can’t see it—Can The Man of Steel drag a decades-old secret into the light? Don’t miss the debut of this red-hot new series from two of comics’ brightest superstars: SCOTT SNYDER and JIM LEE!
This debut issue also includes a bonus two-sided, tipped-in poster measuring 11.6875” x 18.875” that is part of the reading experience and can be easily removed for display!
This issue is also offered as a combo pack edition with a redemption code for a digital download of this issue.

So I really doubt it's a miniseries.

Does anyone else find this sentence a little strange? To me that sounds like it's some pages of the story that would look good on your wall. If that's the case, why would you pull out part of the comic? That'd screw up the flow of the issue and bring down the value.

Or am I wrong, and it means something else?

@V_Scarlotte_Rose: Huh, I didn't notice but that does seem to be the case. I doesn't really make sense so I hope there's a really good explanation for that.

@SmashBrawler:I'm trying to work out what else it could mean. The fact that it's double sided makes me wonder how it can be part of the story, or reading experience, as that would mean that the image on one side would be only visible in two halves when reading the comic.

@SmashBrawler cool thanks dude also how long do you think lee will be on art duty ?

They are not marketing it as a mini series. It has no definite end date as of yet. That being said, who's to say how long any series will last? This one is meant as an ongoing, however.

@Z3RO180: I dunno, he's supposed to be in the book for the first arc (12 issues). We'll have to see if he stays in the book after that. Snyder is definitely staying in the book after those 12 issues, though. Wouldn't make sense for him to leave a title (Swamp Thing) only to do a short stint at another.

@SmashBrawler Thanks dude I have no dout that unchained will epic.

What different would it be from ac and superman ?
