i belive saren will make an appearance in mass effect 2. i have been reading and looking at the recent profiles and pictures of the new geth character legion. i noticed his left arm looks very similar to sarens left arm. saren also seemed to become more and more geth-like in his apperance as the game progressed. also i have heard that legion is obsessed with shepard. if someone killed me i might be a little obsessed to. also legion thinks for himself saren could think for himself even under the effects of sovriegn. just a thought, but if you have any feedback i welcome it.
