Now that the buzz of SEMA 2010 is quietly dying down, the auto world will now set its attention to the forthcoming LA Auto Show on November 19th.

One brand that’s scheduled to be in attendance is Cadillac->ke18 and it’s just come to our attention that the automaker will be bringing an all-new concept car to the City of Angels.

Not surprisingly, the company has kept mum on what kind of car this is going to be so all your guesses are going to be as good as ours. Short of saying, we don’t know what it’s going to be. It could be anything really – maybe it’s even the Aera Concept (pictured above) that they’ve entered at the auto show’s Design Challenge – but for now, all we’ve got are tons of speculation.

In some ways, it’s a good thing not knowing what to expect because it keeps that element of surprise at a high-level. Who knows, these guys might be bringing a car that’s going to revolutionize the world. Highly unlikely, we know, but that’s the beauty of being in the dark when it comes to concept vehicles.
