Sony has been talking to TechRadar, and saying that they are completely committed to OLEDs. They see OLEDs as the next display technology.
Sony however thinks that it'll take a few years (at least) for OLEDs TVs to surpass LCD TVs. Sony want to 'slowly cultivate' their OLED technology - they plan to deliver 'new lifestyle ideas and applications' using OLEDs.
Sony are rumored to be releasing their next-generation OLED TV (The XEL-2?) at IFA 2009. It will be bigger than the XEL-1, at 21" or 27".
