Due to the wait, I decided to play some KOFXII the other day. Man that game still looks amazing. I wish SNKP would bring back those extra effects on the sprites, like the illumination caused by the attacks. If SNKP has the time, they should add them, makes the sprites look more awesome.
I think those effects were rather distracting.
And that's exactly why they won't be coming back

People complained about losing their character in the dark corners and edges, and also having the shiny bright colors on sprites making them blend into the background. The Data for such lighting is still on the sprites, and even on the new ones, as seen with the lightly tinted areas on their bodies in the China and Egypt stages.
I think they could modify the effects some, like have the on-body highlights tinted by the color of projectiles as they approach characters, and to have explosions give off some highlights, but otherwise, this is something I'm willing to compromise, if it makes the game easier for a wider group of people to play.
@ Rex Dart: LoL, yeah, I thought about it too. I'd even perfer something much more pretentious and positive myself, like "Console UPGRADES edition!" or something, haha. There's so little negative coming out of this game's changes, it deserved to be noted how in-touch these ideas are with the characters and players.
