This might be a little O.T. but a lot of movie previews say "now showing in 3D and RealD". What's the difference?

No, it's exactly as I described. The OP didn't ask what's the difference between home 3d and theater 3d, he asked '... why the need for the movie's trailer to say things like "Coming soon, in 3D, and RealD!"', meaning he was wondering how RealD is different from other movie theater 3d implementations, and as I said before, it doesn't in any meaningful way: RealD is just a branding of one of several implementations of 3d that uses circular polarized.
And for that matter, home 3d is not exclusively limited to shutter glasses, there are plenty of implementations that use passive polarized glasses - I've used one myself - but that's not relevant to the topic.
Because if the consumers think a particular format is better, they ask for it, and theaters then have incentive to adopt it.
