802.11n question for my macbook pro

I have got a 15" 2.0ghz macbook pro core duo. I have the airport extreme wireless card built in but for me to get 802.11n am I going to have to get a new chip or is there going to be a driver available later on down the road that is going to allow me to enable my wireless card to get 802.11n?

It was only the MBP C2D that have the n class wireless card.

So am I going to have to upgrade to get 802.11n?

Yeah, I think so. Why do you need it?

I don't need it. I just want it.

Apple is not selling Airport Extreme cards with N yet and they haven't released drivers on their site for the N enabler (although they do come with the new Extreme base station)

I can understand that, but I dont think a normal user wil notice the difference between g and n.
