Update: The terms & conditions for developers to sell via Amazon have been leaked.
Speculation abounds that Amazon is planning their own storefront for selling Android apps, one in which they, not the developers, will set the price and decide which apps to feature (and which apps to exclude from the store all together).

I recently read that by 2012 we could expect 120 app marketplaces, but with some of the largest players now hurrying to get into the game, I doubt this will be the case. For details on the Amazon app market approach, click through and read this excellent post by Andrew Savikas
