After seeing the preview I wonder how many pages the full All Roads will be? Considering 12 pages was a preview I presume It'll be a bit larger than that.
Any educated guesses?

32 (22 if it's not a premium issue) for many comics that are single issues
120 for most Tradepaperbacks, which usually collect a few issues of a single arc.
I'm expecting somewhere between 30 and 60 since it's a one-off.

I've heard the number 60 thrown around a lot for the final page count.

given whos writing it, one too many. . .

that said given the team creating it its going to be good. Its just that Im expecting one too many "Big" images simply to have one big picture.

Eh. :shrug:

From the first twelve pages it looked pretty nice, and the writing was good in my opinion. Do you really find Chris Avellone that bad?

I'm just surprised that they showed so much of it already. Even if this is a 120 page spectacular (pretty doubtful) they've given away 10% of the content.... and even more if it's a shorter book. This coupled with the confirmation of the contents of the package are kinda weird to see so early.
