You really think we need one? I'd figure a thread on the idea would pretty much be
"Hey, did you see ____?"
"Yeah."
"OK, COOL!"
*repeat 20 times*
-close thread-
SVB is repeating what was found at EVO and Otakon, just now with an additional pic or 2.
Now, an interesting bit of discussion on the idea, that someone on ON had, is that the cameos from the past (Charlotte, Kagami, Hanzo), are present because Saiki has unsettled the flow of time, and it's causing odd anomalies that are bringing warriors from different times into the time of KoF.
This is a very, very interesting idea, because it would open up console guest characters from pretty much anything SNKP has ever made.
Gen-an could recognize Mai as his bloodline, Eiji and Zantetsu could team up, Hanzo could be stuck with Malin and Nagase, Kagami could test his flames aganist those of the Kusanagi, Kaede and Rock could see they're brothers from related mothers, Shigen could match powered arms VS Maxima...
I don't even know if we should see this as "unlikely" anymore, lol. The amount of Cameo's popping up from random games in these new stages DOES seem to carry a theme... It would be interesting to see DLC story modes dedicated to random SNKP characters clashing with the KoF cast.
