No.
The Auto Mag, and Silenced SMG are written onto the Halo ODST CD, not the Halo 3 Multiplayer CD (ODST Comes with 2 CDs). So only the CD that has the weapons written onto it will have it, and allow it to be used. Since the Multiplayer one is basiclly a normal Halo 3 CD it won't be adding anything new.
EDIT: As some pointed out, they can be added as Reskined Weapons, but they won't have any of the same properties (Auto Fire, Scope) as the ones in ODST Campign and Firefight!
Also it is very unlikley Bungie would add them in as reskins.like i said, *maybe* that's why Bungie decided to wait to release the new maps (Heretic, Longshore, and Citadel), because they wanted to have these new weapons available on them.
it's a stretch, sure, but it's possible.
also, you say, they're on the ODST disk, not the Halo 3 one. BUT, both games use the SAME engine. so it would be next to nothing to just copy the files and implement them into Halo 3.
