At least with the Conduit, it wasn't that big of a revelation to find out it was simply a portal to the Citadel, Shepard always knew it was either a weapon or SOMETHING that would give Saren an advantage. It's nowhere near the same caliber of twist when you find out the Catalyst is the one that created the Reapers.
