Played the demo for this yesterday - and I'd have to say this is probably the easiest and most fluid version of the demo I've handled. The game plays smoothly and doesn't seem to punish for playing with some recklessness...(although, I think they've dumbed it down some - perfect for my skill level..

).
I tried the two courts, Paris (Clay) and US (Hardcourt) to try and the demo's players include Rafael N. or Roger F. as well as Ana Ivanovic and Serena Williams. This is probably going to be the first Tennis Game I'm going to add to my library, specifically since most of the previous demos haven't really intrigued me as much as this one in terms of visuals and the controlling.
