KoreaTimes reports that next year Samsung plans to shift more investment from LCD to OLED. According to the article, Samsung Display will invest around 6 trillion won (about $5.58 billion), out of which only 29% in LCDs, and the rest (almost $4 billion) in OLED. That's actually lower than the planned $6 billion OLED investment for 2012 (we're not sure how much was the actual investment in 2012 though).

Samsung will invest in both small/medium OLEDs and large ones (OLED TVs). The same reports suggests that Samsung will announce the Galaxy S4 during the Mobile World Congress in February 2013. They are also working on the Galaxy Note 3 - which will have a 6.3" OLED display. OLED TV sales however, are only expected during late 2013, which is not good news.
