I told you:
I actually think that the publishing model of 4e, with printed stuff as well as a subscription model, is valid for a period of transfer only.
What do you mean by "period of transfer" in this context?
I meant a period of transfer between the old publishing model (printed books only) and the new model we can so lovingly speculate about.
There's other options, such as making 5E into a hybrid rpg/boardgame similar to 3E WFRP.
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

.
Paizo's model seems to be the most conservative one, and easy to get used to for existing roleplayers.
FFG's model probably spells a short lifetime of any edition. The high production costs of such games meaning that the foreseeable decline in number of sales for supporting products will bring the "refreshing" new edition marketing rather early.
WotC's model? Frankly, I don't know. I'm rather sure that WotC did some research before going this way, so they should data supporting their decision. If everything works out according to their plan, we'll see 5e as a further step. If the numbers are not reached, we can look forward to some interesting changes...
