I've been thoroughly enjoying mine, though, this is the only game I have (and planned on having short term at least):

I threw it on top of one of my spare KI boards (one must have backups) for scale purposes. I expected a Blu-ray size game case like the rest, but it's massive.
Thus far, my only complaint with the new KI is the clipping. You don't notice it during matches, though, in training mode, if you walk right up to your opponent, instead of overlapping like the original sprite based KI games, the models totally intersect (as in, Sabrewulf's head goes straight through Jago's chest and out his back).
Oh, and I do have a second complaint, and that is, Jago no longer has his slide from KI2. Though, I'll admit, having a character with two ways to completely clear the screen, one that went over low attacks (his standard Wind Kick) and one that went under high attacks and most projectiles (his slide) was a bit unfair (and one of the reasons why Jago was my main in KI2).
Oh, and also, learn from my mistake. Turn off Game Resume if you sunk a ton of time into the free version while you waited on your Pin Ultimate edition to arrive in the mail. Game Resume is awesome in that it throws all games into a suspend state and they instantly resume (and I can go from my XO off to a KI match in about 3 seconds-5 seconds), though, it wouldn't recognize that I had put in my code, since the game wouldn't restart, only resume. I had to turn off Game Resume temporarily and restart my XO so when I launched KI it would actually restart and not just resume and during a restart it rechecks DLC, and then everything was good.
This weekend, with the holidays, family and friends are all piling over here on the 30th for a "next-gen" gathering, and my brother is bringing his PS4, a cousin is bringing his, and a friend is bringing his XO, and I also have my Wii U, so we'll have my XO and my brother's PS4 A/B'd into my receiver, and the other PS4 and XO on the table in our media room hooked up to side by side 24" 1080P monitors (between friends and family, we have copies of most cross platform games to compare for ourselves) and of course, the Wii U is for 4 player Super Mario 3D World.
Long story short, we're all just going to crash and play games and be ignorant of any "console wars", other than to amuse ourselves with our side-by-side Battlefield 4 and Assassin's Creed 4.
Hopefully everyone else is enjoying whatever "next-gen" system they picked up, if any.
