I'm curious as well. It may just mean they're the -11 models with the cross-threaded shafts, but it could be something recent too.
From my brief study and savvy use of search engine ninja skills... I have discovered... absolutely nothing more than what you post here...until this:

... The problems with stock prop fitment is all the white paint that is on the threads and the shaft....
So I suppose matched threading to the Phantom (as the original t-motors did not have that I am reading) and Justgregg points out the liberal use of white paint... at no additional charge.
While there are a couple of mentions in a few spots out in the digital flotsam and jetsam, overall the consensus is exactly as Jg up there says- better balance, better bearings. see many mentions of better response and better performance- but the posts from the folks that give me the best guy instinct they are spot on objective also point out that those improvements are very slight, and only noticeable if you are extremely intimate with flying your quad- which I would like to consider myself, but based on the previous mentioned resources, I am pure, unadulterated pee-pee ****. I got minutes to their hours and days, not to mention the years of r/c flying before there were multi-rotors for the masses.
I am pleased at the investment- I have no regrets for choosing this upgrade (yet) and despite my trimming much off the Phantom on this latest rebuild, I still need to consider that is so I have a buffer for the retracts. I also am looking at stacking another Rx on it to try and get all my gimbal control through that Rx, and then hopefully open up the 5 and 8 channels on the Naza for gain adjustments. Basically I am pretending I have a real aerial photography rig- learning how it all works and coordinates, and then I will build something from scratch.
On a good note about motors- I discovered that I did not have a bent shaft on one stock- so in many ways this upgrade was pointless- I had a bent motor mount on the shell- I was doing mock ups with it today, and noticed it- I put the new shell and guts in and tightened them down enough to fire it up and the motor spins perfectly. I put the props on and started it up- they all are precisely the same distances off the top per my old measurements... so I should have been WAY more thorough before jumping to the conclusion my motor shaft was bent when that prop hit the top- if I had looked closer, and not been so pissed, I would have saved $200.
