What i find odd is that the reapers were supposed to be in deep sleep, because you apparently stopped Saren from opening the relay in the citadel and waking them up. Sovereign was a single reaper who looked over the galaxy while the fleet slept...
Yet they somehow not only woke up, but know about Shepard and all relevant events (hence abduction of colonies, etc)
yesyesyesyesyesyesyes!!!
if they do this, it means they'll be bringing back the mass effect 1 weapon system! where you have your bag of stuff which you carry around =D
