From what I understand, 800 is on it's 3rd revision, though only two have been labeled (800 and 800-2). 800-2 was supposedly revised at some point, but the label stayed the same.
So as far as I know, the most recently updated Portras were the 400s. Followed by the 160s, then by 800. As far as generation of tech, it looks like the 400 is out in the lead, with the 800 and 160s on the same level.
