According to an official TGS 09 information sheet, only 37 Wii, Xbox 360 and PS3 games are to be shown at the Japanese show later this month.
This morning's rumoured MS line-up, listed 18 360 games as playable, while the TGS data says 17.
DS will be by far the most supported console of the show, with 41 games on hand. PSP will see a mere 11 games on the showfloor.
TGS runs from September 24-27. You can see the break-down in the image below. Thanks, Lutz.
