Are Apple planning to sell 3rd Party iPhone/iPod Touch Apps?

Macenstein were talking about Apple charging for other peoples 3rd Party Apps through iTunes, but I watched the Keynote and didn’t pick it up… no other sites seem to be talking about this so is Macenstein just being stupid?
It would be good if they distributed them through iTunes for free like they do for podcasts and iPod Classic Games but surely they can’t charge for other peoples Apps?
