So we have different parties changing the publishing models in different ways:
Paizo tries to bind its customers with subscriptions, offering a substantial discount if you decide to go this way.
FFG tries to give you more "stuff", with lots of physical components appealing to the toy lovers.
WotC tries to change from a (book) publisher to a service provider, reducing the amount of physical components and offering computer support.
There's also a fourth publishing model of White Wolf, purporting to be moving to a DDI type model simultaneously with an MMORPG video game for World of Darkness.
