Sorry for the double post, but this comment deserves more props than I've given it:

Infiniti is rebuilding their whole image around a great V-6, so if the engine is right, the configuration is moot.
But prejudice against Cadillac as a domestic brand means their V6 would have to be spectacular to get any respect for the car wrapped around it. And the specs on GM's high-feature V6 are merely adequate at this point. They would have an easier time getting attention (and sales) with a more prestigious configuration.
Cadillac understood this when they built their V8 with DOHC heads, and the coming V12 certainly shows understanding of the high end. I suppose limited engineering resources dictate that CTS remain adequate. But I fantasize about that V12 being sliced the other way, and I fantasize about XV8-powered rear-drive sedans. I fantasize about Jesse Jane in a tub of chocolate syrup too, but I doubt anyone wants to read about that here.
