Strange indeed, since there wasn't any announcement and also since Maximum Impact 2 was released as "KOF 2006" in the States. This is probably some bullshit. 
I put it on my wishlist anyways. I'll ask the fellows over at the neo-geo.com forums and see if I get a similar opinion. I hope that this is legit, though, and that it's Regulation A with Live multiplayer. 
Those guys don't know squat.

If it gets announced, J-mags will have the info first.
Right now SNK is working on KOF '98 Ultimate Match for the arcade/ps2 and K2 is finishing up the new 3D Samurai Spirits. Regulation A is getting an arcade sequel, BTW.
