Most professional calibrated reviews are already of the 65" models so there are plenty of data points for that. The pro reviews almost never do calibrated large sets so there's almost no good data on them. This particular shoot out has always been of the most expensive consumer tech. They included the biggest Pioneer Kuru Elite's when almost no one could afford them (which is why Pioneer gave up), they then included the Sharp Elite's which were way out of most people's price ranges costing at least double comparable sized sets (which, again, is why they were short lived). So in that tradition it's completely consistent they would review the high-end 4K large panels. This particular shoot out has never been about comparing the most popular affordable panels but the best available panels.
I have to disagree that 65" is a "medium set". Statistically, very few houses have 65" sets, let alone bigger. 55" is probably the largest size with significant numbers. I'd peg 65" squarely as "Large" and anything over 65" as "Extra Large". 90"+ would have to be an extreme category. Medium should really be something that is somewhat reflected as near a majority in actual distribution numbers.
I think the vast majority of people would still consider 55" to be "large". The main question is whether the cutoff to Medium should be at 50" or 46-47", IMO. It's really only the hyper-technical "gotta have the best" AVS crowd that thinks mostly in terms of very large sets.
My personal ratings, which I strongly suspect a majority of non-AVS users would agree with, perhaps +/- 5":
This, of course, puts nearly all projection systems in at least the XL, if not XXL category.
I would really like to see a shootout of L-XL televisions, with a $10k cap to weed out the insanely expensive systems, and a healthy number of $3-6k sets that are actually attainable by a reasonable majority of enthusiast purchasers. Because, personally, outside of perhaps a small LCD in the kitchen (or back of the carseat), I don't have much interest in owning anything less than a 50" set (I MAY be talked into a 46"-class set for the MBR by my wife, who doesn't want every room dominated by a large TV screen!), and considerably larger than that for the main viewing room. I currently have a 65" Panny plasma which I adore for my main viewing room, but there's really nothing semi-reasonable on the market right now in the over 65" class that would be a good substitute, and that mere mortals like myself can afford. The Sammy F8500 would be too small an upgrade, since there's only a small quality difference, and zero size or resolution difference. The OLED sets just aren't available in reasonable numbers yet (esp in the over 65" category), and I still have longevity concerns about these early generations. And 4K LCD tech sets clearly have some distance to go before the catch up with Plasma, let alone OLED, contrast and black levels.
Based on reading this thread, I know I'm not alone in this wish.
