@thomasfxlt continues to update Post #1 of the 2016 P-Series owner's thread with a wealth of information about these displays. There are differences between the M and P Series, but their similarities are far greater. I advise any newcomers to this thread to read the first post over there as it covers many of the often-repeated questions in this thread.

I think we are due for a dedicated thread.
I received my M70-D3 this morning. The delivery company was a few hours ahead of schedule. As the they tapped their feet waiting for me to sign their form, my kids bounced from couch to couch screaming "IT'S SOOO BIG!" Last night I had taken down the tv that is older than both of them, a 2007 50" 720p Panny plasma (which was much heavier than this Vizio). I looked at my old Vann's receipt email... I ordered this Vizio 9 years and 2 days after ordering the plasma. But enough of that I suppose...
I don't have much of a review at this point. I got it unboxed, held my breath until I got the plastic out of the way to see the screen was in pristine shape. Plugged it in, booted it up... flawless. I signed and let the guys go on their way (pointing out the big bold letters by my signature stating to not sign until the unit had been powered on and inspected. Anyhow... be mindful. Whatever they try to tell you, get it out and on and inspected before you let them have the signature.
I'm hardly a videophile -- I usually spoon my play money towards audio (I never even owned a 1080p tv) -- but I will do my best to help out with the evaluation of the display. For now, here are a few pictures I snapped. I couldn't stay home to play for long. Click for full size.
Fortunately I had read past remarks of folks being scared by this screen. If I didn't know the background was supposed to be so blotchy, I might have been worried about uniformity.

I was commanded to put on something for the kids/

Forgive the hanging wires. I will not sleep until that is fixed. The distance from my wall penetration to the ports on this display is far greater than it was on the old one. Longer cables needed.

I'll have more later. Other owners and prospective owners, please chime in.
