So ..it looks like the commoners will be taken care of.
Now (and the moment that we've really been waiting for) ...it all depends on price (ta-da!)
I doubt that Fleetguard is going to bring their cartridge filter elements down to the price that makes it worthwhile. The canister itself will probably be expensive, although cheaper then current market offerings for like products.
