Sorry to see the demo got pulled. I still have it on my HD, unfortunately do not have a capture card.
Here were my impressions. Played one match on the highest difficulty, but the Cliffs' Notes version is that the gameplay falls well short of TS4 as far as realism. More arcadey than sim.
Well the commentary's ok. The gameplay...not as good as TS4 IMO. More arcadey. I just hit a one hand topspin BH with Nadal.

Somewhere between VT and TS. Not truly arcadey but not truly sim either. The presentation is good, Cash and Mac are good on commentary.
I guess I should say the only players available are Djoker and Nadal at Wimbledon.
So the good and bad:
Good:
-Commentary adds to the game...I wish this commentary/presentation was in TS4 though.
-The TRC is a good addition, though I still went back to the buttons by reflex. May be willing to give it more of a try though.
-CPU did make UE's, which is something that can be hard to see from the CPU in TS4 (sorry to compare it to TS4, but I've spent hours upon hours with that game and as the most recent great tennis game to come out it's a good comparison). The W/UE count was more realistic.
Bad:
-Slice strokes don't even look like slice strokes
-Movement is floaty
-Players don't show emotion immediately after points, only in cut scenes. Saved a match point with Nadal and he just stood there like it was nothing.
-Gameplay just doesn't seem that good, certainly not as good as TS4.
That's after only 1 game on the hardest difficulty. Granted it's not god awful, but seeing stuff like Nadal hitting a 1HBH and lack of player emotion takes me out of the experience. I'll play a bit more to give further impressions, but I was disappointed overall, and I'm usually an easy sell.
