SHould I wait to buy a 32" 1080p LCD? For 120HZ?

When do Sony's new models come out? It seems like there really isn't any 120hz models in this size, but Sony has already released the 240hz XBR7.

I almost bought a KDL 32XBR6 tonight, but backed off because of it's only 60hz.

I need a little help trying to figure out if this really matters or not. Also, I already have a 40" XBR6 that is great.
