Like I said before, it's almost like they're seeking out reasons to push back the live date. Damage system, weather, what next? I note we haven't seen any decent in-game shots of the rally content yet either.
But they still have time to go round accurately modelling every single new car that's about to be released and taking thousands of screenshots.
The longer they leave it, the more awesome it's going to need to be to live up to the delays. If they'd released it a few months after Prologue they'd have got away with it, and would've been able to patch any new features in as they went rather than just shouting about them. At this rate, people are going to want the cars to physically jump out of the screen and crush them to death when they crash.
