Star Wars was originally going to have 3 attractions as well but budgets get in the way.Well, Toy Story land is a smaller land, plus The entrance to Toy Story Midway Mania will be in that land too (so 3 rides but 2 new ones)
Pandora was originally supposed to have 3 rides but one got cut for budget reasons (still an expansion spot so can add on to the land) - plus the land itself it like an attraction with all the details (though I feel they under-delivered in the promised level of interactiveness of the land)
Star Wars Land will be similar - 2 major attractions and then the land itself and its inhabitants will be like an attraction
I hear you though, I think adding in a few smaller things would be nice
Star Wars will be unlike anything else though.
