Did you do much research before compiling this list? You missed most of the Konami titles for starters:

"Konami Digital Entertainment, Inc. to showcase a blockbuster line up of new videogames at the 2007 Tokyo Game Show, featuring the world premiere of the first playable Metal Gear Solid 4 for the PLAYSTATION3; a portfolio of new health and fitness-focused games for the Nintendo Wii and Nintendo DS; and brand new Winning Eleven titles. For the first time fans will get the opportunity for hands-on play with the highly anticipated fourth installment in the Metal Gear Solid series. Also in store for franchise fans will be Metal Gear Solid Portable Ops + for the PSP system, Metal Gear Solid Online 2.0 and Metal Gear Solid 2 Bande Desinee, the digital graphic novel.

Konami urges fans to "Move your Body!" with several innovative new NintendoDS titles that leverage popular fitness genres, including Pilates, Yoga and Skin Basic, while Wii Fitness and the brand new Dance Dance Revolution Hottest Party will get players' hearts beating even faster. Big Head Baseball and Big Head MLB for the Nintendo Wii will also be featured for sports fans, along with two new Winning Eleven titles, Winning Eleven 2008 and Winning Eleven 11.

Rounding out this must-see line up is Time Hollow for the Nintendo DS and Silent Hill Origins: Zero that offer gamers pulse-quickening entertainment on the PSP system."

Konami Games announced

Time Hollow (DS)

Pilates (DS) [others were previously announced I believe]

Wii Fitness [Wii]

Big Head Baseball (Wii/PS2)

Big Head MLB (Wii/PS2)

Winning Eleven 11 (Wii/PS3) [I think the others were previously announced]

These games (to my knowledge) were announced just prior to TGS (i.e. that they would be shown at TGS for first time). Include them if you want:

We Love Golf (Wii)

Ousama Monogatari (Wii) [Project O/Kings Story - previously known, but properly announced now]

Mysterious Dungeon: Shiren the Wanderer 3: The Sleeping Princess in Karakuri Mansion (Wii) [announced previously? not sure...]

Active Life: Athletic World (Wii) [the other/other health/fitness game - from Bandai/Namco]

Doraemon Himitsu Douguou Ketteisen (Wii) [not sure...?]

Deca Sporta (Wii) [Hudson - announced just prior to the show]

Metal Slug 7 (DS)

The Legend of Kage 2 (DS) [Just prior to show from memory]

Tank Beat 2 (DS) [???]

Infinite Undiscovery (360) [just prior to show?]

Ninja Gaiden II (360) 

(the ones I found anyway...)

...

(and also some announced "Arcade" titles for the 360:

Japanese developers have long embraced and championed Xbox LIVE Arcade, with hits including “Pac-Man Championship Edition” (NAMCO BANDAI Games), “Bomberman Live” (Hudson Entertainment), “Frogger” (Konami) and “Fatal Fury Special” (SNK PLAYMORE Corp.). Several new titles from these and other Japanese developers will be added to the diverse portfolio of digitally distributed, high-definition original and classic games currently available on Xbox LIVE Arcade, including the following:

“Every Extend Extra Extreme” (Q Entertainment), “EXIT” (Taito), “Ikaruga” (Treasure Co. Ltd.), “OMEGA FIVE” (Hudson Entertainment), “Rez” (Q Entertainment), “Triggerheart Exelica” (Warashi), “Braid” (Number None Inc.), “Castlecrashers” (The Behemoth), and “Schizoid” (Torpex Games LLC).

 ..etc...).

Has Nintendo confirmed that there will be a Nintendo Expo type thing? I didn't think one happened last year...

They will be at the "'E' for Everybody" expo in the US, later this year. This was supposed to be the official replacement for E3 (i.e. the public part of E3).

And neither Sony nor MS will be there (Ninty easily the biggest exhibitor there), so it might be the perfect time for some announcements (hog the spotlight!).

Very few games announced...Motortorm2,Ninja Gaiden 2.....

Most notable would be Kigdom Hearts for the PSP (the DS one seems agimmicky spinoff)....

Wheres Star Ocean4 for example?

Infinite Undiscovery isn't new people. I'ts over a year old.

Simialrly, Star Ocean 4 is no where to be found, but it was announced way back at the SE party in May.

And Victorious Boxers Portable (PSP) isn't exclusive, it's a port of the Wii game.
