They have released statements about Sims 3. Not remastering it, but updating it to be truly 64 bit compatible. Anyone with an up to date Mac can't play it right now because it's not.
I still play Sims 2, but it takes a lot of fiddling with various files to make it work. And I can only play at all because I have a Windows partition set up. (I could play Sims 3 with the partition too, but I could only choose one of them and 2 won).
My ultimate wish would be for them to finish the packs for Mac (they only did a few) and update the game to run on current machines with no tweaking. But I'd settle for continuing to use a Windows partition if I could at least get the updates.
