IMHO, you gotta wait this one out.
OLED technology is still changing pretty rapidly and AFAIK the "blue pixel" issue hasn't been solved, but instead worked around in a way that shouldn't provide much comfort when speculating about the life span for these units.
FWIW, the existing models are not 4k compatible and, altho the max 55" screen size and lack of 4k content might largely moot that anyway, I wouldn't want to pay the asking price for a display that won't handle the highest rez content if/when 4k actually takes off.
OLED feels (to me, anyway) like it's gotten to market in a more half-baked form than most new technologies.
