So let's see if I got everything here:
-
Samurai Shodown II is coming to XBLA!!!!!!!!!!!!!!!!!!!!!!!! 
-
Samurai Spirits Rokuban Shoubu is heading to both the PS2 and Wii. This is a compilation with
SS1-5 and Tenkaichi Kenkakuden, plus online play and color edit. No SS5 Special though, for some dumb reason. You can pretty much bet on not seeing online play for the English release.
-
World Heroes Gorgeous (All four WH games, no Ninja Master's which is also fucking stupid, or Aggressors Of Dark Combat included) is hitting Japan in October for PS2.
-
Metal Slug 7 is coming to DS. It looks pretty fucking good based on the screens, but also 100% recycled, yet again.
-
The King Of Fighters '98 Ultimate Match is coming to both Wii and PS2. This game features 3 selectable play styles (so 1 new) and added characters from KOF '95-'97, meaning Kasumi, Eiji, the boss team, etc. are back. There are also new backgrounds. This will likely end up as the best KOF ever made, period, since '98 is so fucking awesome already. Although it will be hard to top the awesomeness that is the PS2 KOF XI.
-Sunsoft Collection for PS2 will feature
Galaxy Fight and Waku Waku 7.
-
The King Of Fighters Maximum Impact Regulation 'A' 2 was announced for arcades, running on the Taito Type-X2 hardware. This joins the upcoming 3
D Samurai Spirits game and KOF XII, which is now rumored to be a cel-shaded "2.5d" fighter according to Kotaku. I don't know if I believe that since SNK previously said it would be a brand new 2D fighter with new sprites.
There's also some gay DS RPG they're making, and another SNK girls dating sim title.
Pretty much all the PS2 games will have online play, but again...not for the English versions. I wish SNK would step up and either add online play for the Wii ports, or port these games to Xbox 360/PS3 with online play.
The Magic Box has pics up of most of these titles.
