It's looking likely, isn't it? They have steadily been reducing their presence and seem to only have rebranded models on sale, except for one hard to get flagship. Will probably move over to a brand licensing agreement, a la Philips, Sharp, etc in the Americas.
After Panasonic stopped making plasma TVs their US presence dropped to almost zero. The way I see it is that they have never really returned. They are treading water, sadly.
