From IGN:
Like Ashes Cricket, AO Tennis will feature 3D scanned player likenesses and authentic play styles, and it will also feature the extensive customisation options Big Ant traditionally includes in its sports series, like Rugby League Live, Casey Powell Lacrosse, and Don Bradman Cricket/Ashes Cricket. In AO Tennis we’ll be able to create our own players, sponsorship logos, clothing, and even stadiums to play in. The game will also feature an “in-depth career mode”, where players will need to work their way from being ranked 1500th in the world to number one.
Sounds good to me...
