ODST1:well if you've seen the preview there sre going to be SPARTANS, OMEGAS, there shoould be about 70 of them in 2525
only 33 Spartans were left after training and half of them became ill that is why only 33 were left then second group of Spartans came and only 40 were released but they had not been borne in the time Halo wars starts.
We die like true Spartans.
