I highly doubt is going to go anywhere. Most likely Sony and LG will settle out of court, with little to no money involved. The biggest thing that will probably happen is that Sony will agree to drop its lawsuit it has against LG. Though, it probably will hurt sales in about a week when stores run out of their stock. Unless of course this gets settled much quicker.
The one thing I hate about these patents is companies can just get a shit load of them, most of them not being very specific, and sue other companies who even come out with tech similar to their patent. Hell, they don't even have to prove they are really working on the tech, just have to patent the idea.
