Mark Fleischmann posted an earlier blog with these LG speakers. They are strictly prototypes, with no definite plans for production as yet, and if they do produce them they may not reach the US market.

Still, a close inspection revealed that they are indeed using premium drive units. The midrange and tweeter seen in the close-up of the center channel here are from Scan-Speak and Vifa respectively (unless they are clones, which I very much doubt). Both of these are highly respected driver manufacturers, with Scan-Speak making some of the most expensive drivers on the market. These speakers will not be cheap if they reach production.
