Thanks to a helpful message from NH1 on the S2C boards, I have some new information to share with you in regards to this package.

Based on this pre-order page it appears that the Sims Deluxe package will include the base game along with the Nightlife expansion pack. I had hoped it would include a little more, but it’s a start I guess. We’ll probably see the “complete collection” around the time the sims 3 is released …
