According to this CBC article dated January 02, 2013, LG is taking pre-orders on it's OLED display.

LG Electronics Inc. started taking pre-orders on Wednesday for the world's first big TVs that use an advanced display technology promising startlingly clear images on wafer-thin screens.

The South Korean company said the 55-inch TVs, which use a technology called "OLED" and have a price tag of 11 million won ($10,335), will be delivered to buyers in its home market next month. The new TVs will be available in North America, Europe and the rest of Asia before the end of March, LG said in a statement.
I've also read elsewhere on the unofficial OLED website that Samsung has postponed its launch because the technology still hasn't proved to have a working/successful high yield in production. This is evident in the article:

Samsung declined to comment on the availability of its OLED TVs, saying making perfect products is more important than the launch schedule.

I've seen OLED in action only as a professional 24" Sony monitor in 2011. It's image was breathtaking and truly puts to shame our current technologies of Plasma and LCD, both which show good, but very flawed images. I would find it hard to imagine a consumer not seeing the difference between the technologies. In my opinion, it is that obvious. I've become so dissatisfied with the quality of PDPs over the past few years I'm ready for the change. But word also has it that 4K LCD panels may be the bigger push this year rather than OLED.
