Aiport Cards have pre-N now?

[rugbyboy]

Ok, so i'm wanting to make my iMac G5 whizzy and pre-N wireless fast but anyone know if the Airport cards sold by apple now are pre-N compliant or was that a special for the ones put in Mac Pros?

Will there be an updated Airport card?

Or will, like the change from Airport to Airport Extreme make it a different form so i cannae use it?
