Sony RX100, buy or wait?

I'm looking for something that as pocketable as my Canon S100, but better. The Sony RX100 seems to be a good fit. Thing is, I'm not sure about Sony's product cycle, and whether there's a newer rev just right on the corner. Seeing that the RX100 is hardly ever discounted from its MSRP, I don't want to pay close to MSRP for something that is going to be replaced soon.

And for those owning one, what do you guys think about it?
