If the October date is correct, we should be able to confirm via comic store solicitations almost immediately (tomorrow is new releases day, so ask your shop).
An October book wouldn't be listed until the August Previews
, which would be in comic shops on the last Wednesday in July. Suffice it to say, a comic retailer isn't going to be able to confirm or deny.
My guess -- and it's only
a guess -- is that IDW is publishing two volumes -- the first (in October) with issues #1-4, the second (presumably in February 2013) with issues #5-8, and then a hardcover omnibus (since Star Trek/Legion
is getting a hardcover collection) later in 2013, probably September.
A volume in October will get IDW some Christmastime sales. An omnibus next fall will be able to take advantage of the excitement for Who
's 50th anniversary and more Christmastime sales.
