20GB? Is THAT low still manufactured?

Who knows

1. FFVII Remake
2. KH sequal/spinoff
3. FFXIII/Vs XIII
4. Team Ico's new IPs
5. White Knight Story
6. Little Big Planet
7. Home
8. Rumble
9. Resident Evil 5(still need to play 4 tho)
10. A cheaper PS3 (for Sony's sake)

Hopefully, Sony has an awesome show. I can't wait!

EDIT:

 How about you add to the dicussion then? -_-

^
I forgot about Home

anyway Sony will have people surprised this TGS with huge RPG announcements 

7. FFVII Comp - I'm curious what the next game could possibly be.
6. Final Fantasy Haeresis XIII - Everyone's so caught up in the FFVII remake/KH compilation rumors that they forgot there was another FFXIII game floating out there somewhere waiting to be revealed. Though the more I think about it, it may get pushed to the Jump Festa.
5. Tales - same as Castlevania, new games, trailers, whatever from this series...it'll satisfy me
4. Castlevania - Anything from this series.
3. Infinite Undiscovery
2. Star Ocean 1/2 for PSP. There better be some good footage.
1. Star Ocean 4. Period.

In no particular order:

$499 PS3
FFVII Remake (the originall looks cool and I have yet to play it) on PS3
New WKS footage
Home
LittleBigPlanet footage
Next Team Ico game
Mario Kart Wii info (Nintendo's still showing up, right?)
Rumble Sixaxis
Way of the Samurai 3 footage!1!!!1!
A new IP or two from Sony

I'm surprised I'm so hyped about JRPGs now. I never play them. WKS does look damn good, though. :P

About the price, rumble sixaxis, and FFVII remake on ps3, those three things would guarantee second place for the ps3 (and it could possibly compete with the Wii).

10. MGS Online playable demo's.
9. Star Ocean 4 details and trailer.
8. NCSoft MMO multiplatform for PS3 and PSP.
7. Resident Evil 5 realtime footage for both PS3 and 360.
6. Team Ico games announced for PS3 and PSP.
5. White Knight Story playable demo.
4. Kingdom Hearts games announced for all formats.
3. FFXII running realtime footage with provisional release date in 2008.
2. FFVII remade for the PSP, to be released in 2008 and trailer.
1. $399 40Gb PS3 to be released on 1st November 2007.

And as a bonus, Capcom announces a Resident Evil PSP game. 

@ joshmeyers- The Eye of Judgment is a card combat game that sells packed with the PS3 eye at 70$ for both game and Eye.

It comes out October 23 in the US. 

I'll list 20.

20. Firmware update 2.0 for PS3.

19. More Lost Odyssey details. Already showed a lot pre TGS though.

18. More Devil May Cry 4 details. Most of the stuff I need to know is known already though.

17. ASH details on the DS maybe?

16. What is Afrika? I'm 99% sure we will know at TGS.

15. Resident Evil 5- More gameplay footage or a small gameplay demo on display.

14. More White Knight Story gameplay footage and details.

13. Last Remnant info for PS3 and 360.

12. Huxley details for 360/PC, it's been forever since any new info came out on this game.

11. More Metal Gear Online info, gameplay footage.

10. PS3 Rumble.

9. Dead Rising 2 Announcement for 360 and PS3 (hopefully this game gets announced).

8. No More Heroes playable on Wii.

7. LittleBigPlanet Enemies will be revealed at TGS.

6. Any Monster Hunter 3 details for PS3.

5. New Shin Megami Tensei game announced for PS3 (this is going to happen), hopefully a Persona game.

4. Any new FF XIII and/or XIII Versus Info.

3. Details on the new Kingdom Hearts Games.

2. Metal Gear Solid 4 Playable Demo. This has been confirmed for TGS, and I wanna see it!

1. New Team ICO game(s) announcement.

What did you expect? Nintendo is not officially at TGS and MS already showed their big stuff at the pre TGS conference (NG 2 and LO...) so the show will be Sony's out of the three hardware companies.
