I played the demo for it last night, and as a ping pong player for many, many years, I can say, "Holy crap thats awesome" (as far as ping pong goes).  In fact, I'm probably going to have to buy the game just for that.  I'm hopeful that the computer controlled players get much more difficult, but even the 2nd one in the demo wasn't TERRIBLE (still one 5-0, but there were some decently long rallies).  I really don't even care if any of the other games are any good, ping pong was so accurate compared to the real thing it's almost shocking.  Te only thing its missing is you can't really dive for balls (as you dont really move the player), and the ball seemed to stay on the table a little to easily.  But I'm still incredibly impressed.  Were the ping-pong games on the Wii this good?  (Not trying to start a fight, I just never got them, assuming a game couldn't recreate the subtle movements and their effect this well).

On Wii Play no, on Wii Sports Resort I like it more but it's also different, like the Sports Champions demo you don't control the character simply the paddel, it's a bit more simple and streamlined and I like it that way, the demo for Sports Champions seems like a bridge of realism and the arcade nature of WSR, so to each their own but I hear Sports Champions becomes more simulated later on though apparently (from a few comments and reviews) hitting balls hit down the center of the table is needlessly hard.
