Source engine = no ADS?

The bigger and more varied the environment(stuff like cover and elevation) the more critical it is to be able to aim down your gun-sights.

But since this is source, it probably wont be included right?

If this is the case, weapons should all have at least some moderate level of scope.

The engine itself doesn't determine those kind of game features - rest assured that are weapons are all as multi-dimensional as the biggest and greatest FPS titles- and yes, that includes iron sights :)

(DoD:S had iron-sights too, btw!)

And there are plenty of other Source engine mods who have it as well, Insurgency, Resistance & Liberation, and I'm sure there's others I'm missing.

Even the GoldSource Engine has ironsights (mods like Paranoia and Hostile Intent), so almost anything is possible, really.
