On Tuesday, September 16 at 10PM PT / September 17 at 1AM ET (3PM AU Wednesday, 6PM UK Tuesday), Sony is holding an event ahead of this year's Tokyo Game Show. You can watch the PlayStation press conference live right here on IGN.
Sony previously stated it would reveal two new PlayStation 4 games at TGS -- so keep an eye out for IGN's coverage of those announcements and more during the Japanese event.

EDIT:
That's just the Asia session of the same pre-TGS press conference they already held for Japan. There will likely be release info and pricing for things specific to the Asia region, but it is unlikely that there will be any actual new announcements. Anything which wasn't announced at the Japanese conference will likely be saved for the TGS show floor.
