Forza Motorsport to ship on 2 discs!? What?

I know that Forza 3 will be shipping on 2 discs because it is such a massive game, but one thing is bothering me. Since both the discs won't be able to be in the 360 at once (obviously), do you think there will be a feature to be able to install one of the two discs and have the other disc playing and contain all the features from the one that is installed?Forza Motorsport to ship on 2 discs!?

Games that are divided onto separate discs save your information to the console, so you can carry over your profile/saves/whatever between the discs. This is how it works for many RPGs that come on 2 or even 4 discs. To answer your question directly, you will not be able to install one disc and play the other simultaneously. Your game info will apply to both discs, so you just change them whenever the game prompts you.Forza Motorsport to ship on 2 discs!? What?
From What i heard you install the 2nd disk before you play to your hard drive then play the first disk. I would need someone to confirm please
