Ok, so where's the Gallardo replacement?

So we now have the Aventador, which has taken the empty throne left by the Murcielago. The Murc was my childhood dream car, so I was a little sad when it was axed. But I've come around and I think I like new one better than the bat. But now I have to wonder, what about the Gallardo? Sure, it's gorgeous looks are matched by it's equally sweet engine noise, but it's starting to get on in years. The Ferrari 458 Italia, the McLaren MP-14C, these rivals have burst onto the scene and are a step ahead. The Gallardo is a gold mine for Lambo, best selling supercar I believe? So what's next? Another face lift, or a replacement? I appreciate it!
