You can generalize the debate of in-line vs V because it's the same debate regardless of the number of cylinders. The same argument about balance can be addressed toward the S85 V10 (or any V10 for that matter) but as we all know the Vee configuration allows such a large capacity and cylinder count to fit in a relatively small engine bay which wouldn't be possible with any other configuration. My argument is that the Pros for a Vee configuration far outweigh the Cons. You are entitled to your opinion (no matter how wrong it is) but being able to reduce the dimensions of an engine is the biggest plus possible to an engineer. P.S. I notice you changed your wording to state 'recent'. In any case the reason why Ferrari no long build a V6 is that their model and performance line up are beyond what a N/A V6 engine would have been capable of, but I wouldn't be at all surprised if it the future Ferrari return to V6 power, only this time it will be combined with turbos.
