During work today, I had a thought: The Reapers are obviously hundreds of thousands of light years away from the Milky Way if they can see the entire span of it. Unless they plan to use a previously unknown mass relay to get to the Milky Way, it will take them thousands of years to get to even the edge of the Milky Way traveling under FTL speeds.
If they are 100,000 ly away, it will take them ~ 22 years to arrive based on the typical FTL speed of ~4500 C (aka 12 lightyears per day, given by the codex).
Me and one of the guys in another thread worked out an approximately 2 year transit time from where they are based on the assumption that the entire milky way is present, and the two edges are on a 90 degree angle from where they are. Actually it will be less than this, since we can't see the whole milky way, but it gives us a nice upper limit.
That said:
- Reapers can presumably travel faster than normal MEverse ships.
- Drive core charge problem.
The harder you work your drive core, the more it builds up a charge. Although it's very unlikely that they are so far away that FTL travel couldn't get them there in time, it
is likely that since there is nowhere to discharge into when in darkspace (aka the galactic void), they simply can't maintain FTL cruise speed for years or even weeks. The reapers in the final cutscene of ME2 were not in FTL travel.
At STL speeds, they're thousands of years away.
ME3 will probably feature a climactic battle against some Reapers, but I doubt it will be the full fleet. They will find some other back door in, using some other undisclosed agents still in the milky way.
