One thing to keep in mind when comparing manufacturer's specs on volume 
is that they all measure volume in different ways.  Some don't even 
measure, they just use formulas to guess.  Many fill them up with a given 
substance and then pour it out and measure the vol. of however much it 
fit.  Using this method, vol. will vary according to the size of whatever 
they were using.  For example - you will get a more accurate measurement 
of volume using pistachios than beach balls because of all the empty 
space between the beach balls that won't fill up.

I believe Dana uses ping-pong balls, Jandd uses some sort of small bean 
(like lentils or something) for greater accuracy.  I would recommend 
calling Arc Teryx customer service and asking them how they measure.  

For what it's worth, I LOVE my Bora 40, and that is the old design, I 
hear the new one is even better.

Good luck,
