I'm not sure where you heard this, but it's not true. Any display should be capable of the black levels required for an accurate 10%stim. Assuming 100 cd/m² brightness and 2.40 gamma, the darkest that's ever going to be is 0.4 cd/m². If you use BT.1886 gamma (compensated curve) or 2.22 (0.6 cd/m²) it's going to be even less challenging.

The ELITE doesn't have this problem because it doesn't totally turn off it's pixels.
I would argue that the reason for the Elite having less noticeable blooming is due to the fact that it has a higher contrast LCD panel, and more local dimming zones. Even the top-end Sony has something like 1/3 the zones if I recall correctly.
There are modes on the Sony sets which also don't turn the LEDs off with black, and blooming can still be visible then. What the Elite does should
make a difference to off-axis viewing, however.
I would actually argue that in many respects, the older HX909 was a better set than the HX929. The HX929 was essentially a cost-cut version, as evidenced by a number of problems that exist on the 929 that did not on the 909 with its superior Sharp UV²A RGB LCD panel. (rather than RGBY) Sony themselves discussed the fact that this was the goal of their 2011 sets, as the TV division is hemorrhaging money. The lack of a high-end 2012 model is an extension of that goal.
As much as I like Sony's LCDs, I would absolutely not argue that they are the best TVs ever made, that they were "smeared" in the previous shootout (mistakes happen) or that they should have been included in this one. If it was included in this shootout, a Kuro should have been too. I think it would have been interesting to have a Kuro there for comparison, but as they have not been available for years now, they are becoming less relevant.
For my personal preferences, I would probably place Sony's LCDs in the top spot, as I cannot tolerate issues that exist on all PDPs such as ABL circuits, dithering, posterisation, image retention, flicker, low contrast in bright conditions, and "phosphor lag" but I accept that most people do not have a problem with that.
I need a display that is suitable as a PC monitor (can't have an ABL circuit) for playing games with a lot of static HUD elements (can't be susceptible to IR) is suitable for daytime use in a bright room (even my 909 is not bright enough at times) can play back 24p content without giving me a headache (must support interpolation without introducing the soap opera effect, which I haven't yet found on a PDP) and can display high contrast material in a dark room without giving me a headache. (no flicker, phosphor lag or other temporal issues)
Even my 909 is not perfect in these regards. While the Sharp panel is fast and high contrast, it suffers from the strange subpixel driving problem that has plagued Sharp LCD panels for years, where horizontal lines can look "ragged" depending on the image being displayed. The fact that this is visible even at a distance, when it's a difference of half a subpixel, is clear evidence that 1080p is not enough resolution yet, and particularly impacts the display of PC/game content. I eagerly await the introduction of 4K OLED displays that use a horizontal RGB stripe subpixel structure, rather than the RGBW or vertical RGB stripes on the sets being introduced this year. (I suspect they're also going to utilise ABL circuitry)
Unfortunately it looks like there probably aren't going to be any more high end LCD displays from this point onwards. Everyone has moved towards producing edge-lit sets, and I don't believe Sharp will ever make a truly high end display, no matter how they market and price it.

It seems like it should have qualified under the revised rules to be included, unless a unit was not available in time for the competition.
LG's IPS panels just aren't high enough contrast to support good local dimming without a lot of visible blooming. And if I remember correctly, while the LG nano sets technically have a large number of "zones" there are actually a very limited number of addressable zones that are dimmed, something around 100 or so. It seems more like LG count clusters of LEDs as zones, rather than the number of areas which can be independently adjusted. (whereas Sony uses something like 10 LEDs per zone, and only counts that as a single zone) I wouldn't expect LG to implement very good image processing to back up the capabilities of the panel/backlight array anyway.

3D might be "better" on it, but 3D in general is still poor on any flat panel. The only 3D I've ever seen which has been acceptable, has been Sony's HMZ-T1 OLED head-mounted display, but that is a relatively low contrast display (0.02 cd/m² black level) has very poor optics (lots
of chromatic aberrations) is very uncomfortable to wear, and despite the marketing claims, displays a fairly small image. It also suffered from some bad crosstalk with PC content from what I saw. (not 3D "crosstalk" but horizontal "banding" as seen on PDPs)
