No, we're happy because T10 does deliver. No standard cars in FM4, no half-assed features so far, either. I'd rather have that than a game that tries to do everything but, in the end, is mediocre at almost everything it does.
GT5 is the jack-of-all-trades. Forza 4 attempts to do less things, but sets out to master them, so to speak. For me, and many others, it seems, doing less things but doing them right is the way to go.
And this comes from someone who's ignoring the screen tearing and frame rate drops in GT5, defending the flickering shadows and aliasing smoke

As it seems, PD can get away with half-assing basically every feature there is and it's all perfectly fine and dandy? Well, whatever floats your boat.

And I guess this is where we differ so much

I'd rather go and buy, say, Dirt 3 for my rally fix than to get the watered-down experience that GT5 has to offer.
Hence, I'd rather see GT focusing on the stuff it can do well.
