Actually, these screens are all from pre-E3. Half of those screens were released during the MTV promo, I guess these screens just made it out right now. If it was a recent version of Perfect Dark zero, we would be seeing a different map (marketing strategies, history of game promos - never show the same thing twice).
Also, if it was a new batch, they wouldn't show old pics and new pics mishmashed together. All of these screens are from the only publicly recorded and documented (through pictures and videos) preview of the game, at the MTV promo.
All of these screen are technically 'old', we just haven't seen them until now.
Still a great find, Deftech.
