Great news!

I believe that this will be the second largest DCU archive volume, with only Doc Fate exceeding it.

It remains to be seen though if this will be the new "standard" size. It's possible that they're experimenting with a different price point/page count.

"As for contentment, that is a myth.  Give a man everything he wishes and he will be unhappy, because he didn't wish for more; give him more, and he will die of his worries.  Only a turtle, asleep on a sunny log, knows contentment!"
