Well I haven't actually seen that in written form. Do you have any official references on it?

I also believe the smart thing to do would be to make it available for testing and feedback with warnings about leaving Chapter 1 for those who do not wish to venture beyond - it's win-win for them so why not?

Besides many games suffer from narrative crumbling in later chapters so I'd think more feedback could only be welcome (do you think ME3 3 colored ending would have made it through playtesting - and how much headache could be avoided that way)
