I just spotted Showcase Presents: The Flash Volume 3 on Amazon with a release date of August 11, 2009.
No word on contents yet, but assuming it’s the same length as the last two volumes, it’s likely to contain the stories from The Flash v1 #141–161.
Sweet! I f-ing love the first two volumes. 500 pages of Flash madness for less than 20 bucks! Sign me up. This is going to be a great year for the Flash mythos, especially in trades.
