The full verson is on usenet now. This was a brilliant, highly playable game on the 360, believe it or not. Its not a boring game of Table Tennis like the rest. I don't know how this will work on the Wii. The 360 version used vibrations to tell you when the ball was going to leave the table. So the stronger the vibration the more you knew it would go off the side of the table. When you got good at it, you could play the ball so it hits the corner of the table. That gives your opponent no chance.
This was also a good online game. As usual it looks like the wii has missed out online wise. I've played the 360 version to death. So I'll post again when I've played the wii version.
EDIT: This is a great game but lacks some of the 360 features. The serving can be tricky until you listen to the sounds and can then serve. It will be an exhausting game as my fingers got sore on the 360 controller. This is a lot more hard work having to swing the wiimote. I would say this is one of the better games on the wii. I'm surprised it hasn't had a lot more comments.
