Who knows. Perhaps Anno is going all loldeep metacommentary on otakudom obsession on teenage bishoujos again?
Or maybe, just maybe, with all this curse of eva thing and unaging Eva pilots they're FINALLY attempting to do something with the whole "huurrr durr only 14 year olds can pilot Eva" that got NEVER explained properly in NGE, plausible fanwank about chambers of guf and being born after second impact aside (then again I could swear some of Shinji's classmates were born before)
As long as curse of Eva doesn't remain simple plot device to let the girls have the same looks as always I consider this clear improvement on NGE's handling.
Well I wonder. Maybe it becomes apparent in the film? Even based on limited info we now have one should be obvious: You don't kickup and build apparently pretty big organization like Will-E (why the stupid - is there anyway) in matter of months.
Etc.
