It has been announced today that Sony Computer Entertainment President Ken Kutaragi will make a keynote address at this year's Tokyo Game Show, replacing Nintendo's president Satoru Iwata who had last year used the platform to highlight the until-then secret functionality offered by the Wii controller.

Kutaragi's presentation will be titled, "Next Generation Entertainment Made by the PS3" and will no doubt be the big news of TGS 2006, whether it go well, or not so well.

The show, due to take place between the 22nd and 24th of September, is seen by many as representing Sony's last chance to win over the sceptics its PlayStation 3 push to date has so easily attracted. The PS3 has been caught in a constant shitstorm of some kind or another, be it price, performance, basic design, controller and the machine has been deprived of some of the more positive attention it arguably deserves.

It's also worthy of note that given the magnitude of recent Iwata TGS keynotes, a great deal is expected from Kutaragi. Final global pricing, release allocations and dates, launch line-up and more should be on offer.

The Sony man will be joined in the latter part of his time on stage by Square-Enix president Yoichi Wada, who will be assuming his secret identity of Computer Entertainment Software Association (CESA) chairman, discussing "The Game Industry's Potential and Problems".

We'll bring you full coverage as it happens. Stay tuned.
