In case there was any doubt, it looks like the 3 LSHes will be the 
current version of the original, the Legionnaires, and the current LSH, 
with the "5 Year Gap" LSH being dropped.

And does Superman remember the Legion from Final Night?  Batman's memory 
showed him there, but Superman never said anything about it one way or 
the other.

And I wonder if that Legion will be pre-Legion Lost since there were a 
lot of big changes during that time period?
