They won't, but the point is that Maemo 5 essentially specifies that all apps can always assume an available internet connection. Nokia won't be releasing a non-WWAN version, because the likelihood of the user "failing" to provide a connection is much higher, and they don't want to undermine their spec that way.

I really would be displeased if they did split it like that, as I want different combinations of options. The physical (keyboard, camera) features are highly orthogonal to radio (HSPA) options. But as I said, I'm pretty sure they'll all have WWAN (HSPA; possibly a WiMAX version at some point).
