It sounds to me from that article like Crosman will simply become a North American (USA at the very least) distributor of CA guns. I don't think we'll see the regular line of CA metal guns suffer from this. And it sounds like Crosman will have its own new line of airsoft guns too - I would suspect more than likely rebranded CA Sportsline guns.
Time will tell, but I don't necessarily see this as a bad thing. And I don't see any CA guns making it to the Canadian market any more than now, except maybe the new Crosman line.
