not a fan of MJ... but as a psych student, i believe it's not only Vitiligo, but possibly also body dysmorphic disorder, which would explain the plastic surgery, mental state, and face mask (most of these coencide with Vitiligo as well)
anyway, there is supposedly a video of sims 3 preview in free time expansion pack, and they've addressed some of the concerns, but it may not be everything we've hoped and dreamt for.
http://youtube.com/watch?v=8xTipLHIj4sI myself was hoping for different heights and more body types, but it does seem to address the concerns of shoe choices and possibly layers. There is a more realistic look to them, and they can seem to 'wander' the city instead of being stuck in one place or another, a real type city is rather exciting! and while many people have made mention that it didn't look good enough to buy, I already know i'll be purchasing it. From the preview, i can tell that they've already acheived a great deal and come a long way from where they were. I myself am anticipating the release of free time so that i can see the video for myself in a better qaulity.
Also, i was noticing the other day when you start up the game, (of those of you who have bon voyage) you'll notice the panel that pops up showing you which games you do, or don't have. I noticed that there is enough room for definate on the expansion side for one more, which would be Free time, and on the Stuff pack side, there is enough room for two more icons. Which we already know that it's going to be the designer bathroom and kitchen stuff pack...
http://thesims2.ea.com/about/sp7_index.php i'm extremely excited about that, cause i love my sim kitchens like i love my kitchen in the real world. but there does seem to be enough room for one more stuff pack. I should have screen shots on my other comp and will try to remember to load them.
