Gaming site GameShark has posted a preview of The Sims, with a little interview at the end. There are some screenshots with it as well, of which most were already spotted on 20 May. Besides mentioning the generations stuff and several other things, they also mention the new architectural possibilities of the game:

"The setup is still basically the same. You'll have a neighborhood in which you can choose a lot to build your house. Houses are a bit more complex now, with the ability to build above two levels, build on hills, set down foundations, and adjust angles for staircases between multi-leveled decks…pretty good stuff for Sims architecture junkies. The whole thing is topped off with a new graphical engine that puts the old Sims to shame. Deeply immersing graphics provide visual feedback in place of the attribute indicator bars of old. If your Sim is lazy, he'll get a little chubbier. If you want him to lose weight, a little time on the exercise equipment will trim him down. This is all accompanied by visual cues that literally show all of the attributes on screen."

The little interview (3 questions) tells us a community space is being considered, there might some time be an expansion that brings The Sims to their work, and the time compression may be fine-tuned a bit more so Sims don't spend 30 minutes doing their business. You can read the whole preview plus interview and see the screenshots right here. Thanks to The Sims Choice for the tip.
