Introducing The Sims 4 Get Famous

It seems like it would be interesting. Gives us more opportunities for story telling and adding more to the game play (though I say we still need a story progression, a way to drag needs and a chemistry system),etc.....

I want to know to know more about it. Would the celebrity system be better than that in Sims 3 (like they don't just get noticed by working on skills; but depending on the career they are pursuing? It makes more sense that way)? Can we create bands? That is what I am waiting for (well that and an Island getaway).
