I recently bought the set (from MC yesterday) and I'm a big football and hockey guy and this tv does a great job. Like mentioned before, it's not perfect, maybe plasma would handle this better but the PQ can't be touched by a plasma if you want a pic that pops. This is from a Panny S50 owner and although that's no ZT60, it's still a plasma and the PQ will never pop like an LED, let a lone an OLED so I'm willing to have great motion, ultimate pic vs ultimate motion, good/great PQ.
As for the curved look, I'm not a curved tv guy but this tv is barely curved. Sitting on all sides of the room, the curve is not an issue and it's def not a matter of drawing straws since the corner seats are not at that much of a disadvantage. Viewing angle is amazing on OLED so no one suffers like LED (flat too).
at 2k, this tv is an absolute steal. This is an OLED folks and at 55 inches, 4k won't even make a diff. I agree that 65 4k is the sweet spot (for me as well) but those will be very expensive and will likely take 3-4 years to get to 2k or less. By then you can sell this set and buy that, enjoying 4 years of OLED quality. By then 4k might actually have more content so it's a win win.
btw - this tv just turns heads. I've had some folks drop by who don't even care about TV and was like what is this. With the super super thin profile, curved look (it does look really really classy), carbon fiber back and amazing PQ, it really stands out, more than any other tv in some time.
One other thing - I'm a guy who loves pop and doesn't care if it's not technically correct, etc. Therefore when I got this set I def didn't put it on Vivid but not cinema either as I value over saturated colors. Therefore, for me, this tv is a dream as it takes that LED look and gives it true blacks (Kuro, ZT, etc) and hopefully don't have to worry about IR (haven't seen any yet). I game as well and with game mode, it's not an issue. Great tv.
