Yes, Bkeef's catch can is on the breather (make-up air) hose, which is still venting to atmosphere. This was done just to avoid oil coming out of the breather, and has nothing to do with keeping oil vapors out of the intake.

An ideal system would have 2 catch cans and a completely closed system for the crankcase ventilation.

1) From the PCV valve (rear engine right/passenger side) -> catch can -> check valve -> intake manifold (AFTER turbo/supercharger, where boost may exist). A catch can here would remove oil from the air that is sucked in while cruising at light/moderate engine loads or idling. This should theoretically improve engine feel/performance during normal daily driving type situations.

2) From engine breather (rear engine left/driver side) -> catch can -> intake system (BEFORE turbo/supercharger, where boost will NEVER exist). A catch can here will remove oil from air that is pushed out of the crankcase by piston blow-by gasses when on boost, and should improve full throttle performance.

The current Prodigy setup simply avoids detrimental effects of oil vapors during full throttle boost by venting the crankcase breather to atmosphere. Good for performance, bad for the environment, and annoying to the nose on a warm day with the top down.
