There are already collectible card elements being introduced. IIRC, they are called Feat Cards or something along those lines and are used by the rpga for tournament play and such....
Well, that's almost completely wrong, but it's an understandable mistake, really.
The RPGA player reward cards are collectable - except it's pretty easy to get complete sets without even trying, by playing lots of the Living games. And, they're only legal *in* the living games, so you don't need them unless you've already got them. (I'm not even trying, and they just sent me a full set of the second set of the Eberron cards.)
They're not Feat cards - they're more like specific hero points - they give you a little ability you can use in pretty narrow situations which can be useful. Such as one that lets you take action in a surprise round if you're surprised, or one that maximizes a healing spell when you're casting it on someone at negative hit points. They're useful, but you only get a limited number (1 per 4 character levels) and I forget mine most of the time. Other ones let you play restricted races (such as the psychic guys from Eberron) or give you a minor advantage from coming from a specific place, or such. (And the ones you use for character creation count in the limitations.)
And the RPGA doesn't do tournements anymore, more's the pity. Those were some good modules, too.
So, barely collectable, not feats at all, and not used for tournement play or home games. It's just something to send out to people to encourage play in Living Greyhawk and the like, and to promote the new Living Eberron campaign they started up.
Personally, I don't think a collectable roleplaying game would be popular. Either the cards aren't necessary as cards - in which case people would collect the text of the cards online and people would play without them - or the card form would be too much a part of play, and people just don't play card-based RPGs, on the whole.
