Yep. There will never be a way to counterfeit the power 9, duals, etc.. to pass detailed inspection by the collector guys UNLESS they manage to reproduce the actual way the cards were printed, but that's practically impossible from what I've heard. i.e. they get the same printing presses (which is the almost impossible part), get the original molds or recreate perfect ones, get ahold of the same inks and papers, etc..
But, for cards that won't be inspected by the collector guys, such as most modern and some legacy stuff, they could get close enough that most people won't be able to tell. I could see them getting to the point that even most local shop owners won't be able to tell and will buy/sell them with normal cards on accident. If it's under the $50-100 range, most people won't notice. If they ever manage to recreate the rosette pattern, that's when things will go off the deep end.
