I don't know. It's been a long long time since the original LE's came out and based on past Sin City publication history I wouldn't count on it. It seems that Dark Horse will continue to reprint them but always in a different format. Think about all the different ways it's been collected over the years. TPBs, small tpbs, hardcovers, LE's, the big omnibus, etc.
Now, if I recall correctly, it's being collected in artist edition format.
