Showa Denko K.K. (SDK) has published their 2011-2015 business plan. Their R&D strategy includes four priority items, one of them being OLED Lighting. Their plan is to produce 80lm/W 40,000 hours white OLEDs in 2015. They say that the cost will be ¥4 per lm - which means $3.8 for the 80lm/W device - but they do not specify the size (area) of those OLEDs.
Back in July 2009 SDK has unveild 30lm/W white OLEDs, which achieved about 40% in light output and featured a lifetime of 10,000 hours. Showa Denko are using a combination of printable phosphorescent polymer and proprietary device structure. They also claim that they already begun shipping sample panels. Here's the relevant slide from their plan presentation:
