The Sims has always been my guilty pleasure as a gamer, and it looks like EA is making an effort to make Sims 3 a true "three" game for the series...it looks like the devs started out with a great concept, refined it to a T in the second game, then took the series in a whole new direction for the third installment.
EA's announced that the DRM will be disc-check only (yes, I'm aware that SecuROM will be the disc-checking utility of choice, but that doesn't bother me---it's install-limit and other more draconian DRM that bothers me), and if Spore's eventual release on Steam is anything to go by, EA may be playing nice enough that I won't have to feel like pirating it is my only option---if it's available through Steam I'll very likely buy it through that channel to let EA know that "yes, I approve of what you're doing, and you're going a long way toward restoring your reputation."
As for expansions, if they pop one out every six months and have the same track record for making the expansions actually worth buying (every Sims 2 pack has something to recommend it if you like the core game, and Nightlife and Seasons in particular were extremely well done), then as I see it, what's another 30 bucks twice a year to keep a game fresh? I just hope they're not really foolish enough to think they can charge twenty bucks for "stuff packs" when you can go to any modders' resource on the Internet and just download better stuff for free.
