You've already seen some of the classic suits adapted to the game's style. It's not an exact copy and I'd assume it will be tailored to the Catwoman model they already have. Sale's suit has a very unique mask so that will probably differentiate it from the classic look a bit.Tim Sale's Catwoman is just an uglified version of the classic 80s/90s version. Is it actually in his style, or just wearing the purple suit?
All-Star are simply arcs with no continuity restrictions, and could probably meld with the current timeline sans a few minor hiccups. Earth One is a complete reboot from the ground up. A different universe altogether. Think of it as Marvel's 616 and Ultimate line, except in graphic novel format.By the way, how does "Earth 1" differ from "All Star" as a concept? Other than not being written by Frank Miller and not being lame?
Geoff Johns (writer) and Gary Frank (artist) speak on it a bit. Little info is known. It's not due until May of next year.
