The numbers that have been floating around for inclusion into the iAds are in the millions. You don't get to be part of iAds unless you have serious money, so I think we can assume Apple's going to at least cover their costs.
As for seeing iAds elsewhere - perhaps, but it seems unlikely. Still, Apple's take on ads is that they want to make ads people like. The example he demonstrated, the Toy Story 3 ad, is something I can honestly see myself playing around with for a while. It's entertaining, it's involving. It's not going to be boring, garish text ads like Google ads, uglying up the page.
There's something to be said for the idea of adding taste and style back into online advertising.
