This week's SimDay there are really just a few things. The first is a multi-functional snowman object, with which your Sims can play in the snow. The snow doesn't melt as it's fake:

"Have a ball building your own snowman! Each of the pieces of this versatile set are stackable, and can add up to a snowman or anything else you can imagine. The snowman base and middle sections can be used alone as unique coffee tables, or stacked to reach greater heights. Made out of non-melting snow substitute for indoor or outdoor use year-round."

Furthermore there's a link to the GameSpy article we mentioned Tuesday. And of course there's the Sims 2 University developer chat tonight, which was announced last Monday.
