With live-action broadcast sport, it is also going to require frame interpolation and result in the SOE, but no one complains about that (in this case it turned video into better video).
If I was you, I would separate my watching into the two classes, 24fps cinema (blue rays) and video.
To get a low level of motion blur on video, you should probably not be worried about frame interpolation and the SOE and go for the fastest 'action rate' that you can afford (at least 120Hz).
For Cinema, you probably want to try a set that supports a 'true' 24fps (48fps) Cinema mode. This will not provide any motion blur reduction on a movie but will present it exactly as it is presented in a movie theater. If your wife does not complain about motion blur when watching a movie in a movie theater, she will probably be happy with a true cinema mode.
If you just want 1080p, the 65" 2014 Vizio M Series is $1500 and he 70" is $1900. The native refresh rate of the LCD is 120Hz with a Clear Action Rate of 720Hz which I am expecting to deliver a 'true' Effective Refresh Rate of 360Hz. The motion blur reduction at that Effecive Refresh Rate would be 83% lower than a straight 60Hz LCD (or about 2 times the motion blur of plasma, which is about 10% of a 60Hz LCD motion blur). It should be able to support a true 24fps Cinema mode but the specs don't make clear if that feature will be included or not. The M is not out yet but is expected before the end of March (though nothing yet confirmed).
If you are willing to spend a bit more, you might consider the 4K Vizio P Series. 65" is $2200 but it is also not available yet (hopefully before mid-year). It's main selling feature over the M Series is the higher resolution of 4K over 1080p, but is should also have a better local dimming performance (64 dimming zones versus 32 on the M) as well better motion blur reduction. It claims an action rate of 9600 but I suspect this is inflated and am instead expecting the P Series to deliver a 'true' Effective Refresh of 480Hz. At that Effective Refresh Rate, the P Series would deliver a motion blur reduction that is 87% lower than a straight 60Hz LCD (or 1.3 times the motion blur of plasma). The P Series is specified to support a True Cinema Mode of both 24fps and 48 fps.
If you are unable to wait for either the Vizio M or the P, you might think about checking out the Vizio E with your wife. The 60" is only $900 and is expected to be available by next week, the 65" is only $1200 and will hopefully be available on the heals of the 65", and the 70" is only $1600 and will hopefully be available by mid-March or so. The E-Series is only a 60Hz native refresh panel with an Effective Refresh rate of 120Hz, so the motion blur will be 50% of a straight 60Hz panel (and 5X the motion blur of a plasma). If will not be able to support a 48fps True Cinema mode and will probably also not support a 24fps True Cinema Mode, so playing Blue Ray or other 24fps content, it will probably use 3"2 pulldown which will mean some judder. This might be a useful set to check out at a BestBuy, especially if they allow you to play with the settings and play a Blueray, to narrow down on the viewing requirements for your wife.
If you don't need the dark levels and shadow detail plasma, there are a lot of economical 1080p edge-lit sets that might fit your requirements. Best place to ask that question would probably be on the 'help-me-choose-an-LCD' thread: http://www.avsforum.com/t/1230050/the-help-me-choose-an-lcd-thread
The Samsung F8000 is considered one of the best edge-lit LCDs out there right now, but it looks like it is out of your price range ($3100 for a 65").
The 70" 2013 Vizio M-Series is $2200 and is available now, so that may be another set you want to check out with your wife at best buy. It has an Effective Refresh Rate of 240Hz, so should have 25% the motion blur of a straight 60Hz panel (2.5X the motion blur of plasma)...
