Any "guesstimates' on when 60Hz 4K gaming will be possible on 4K monitors?

http://hardforum.com – Been following the news and some of the threads here re: 4K with great interest. I currently game on 3 30"s in portrait mode (4800x2560) and while I love all that screen real estate, I do look forward to the day when I can game at a comparable resolution (anything over 4,000 horizontal) on one 4K monitor, finally doing away with the interrupting bezels inherent in a 3 monitor setup. From what I've read, to game at 4K now, 30HZ refresh rate seems to be the norm...which is way too low. So I'm wondering when 4K monitors will be able to run games at the monitor's native resolution at 6 (Hardware)
