Yes, when you look at the Top Spin 4 demo for example, I could not see, that they changed something about the animations.
Everyone was complaining about Federers serve animation for example before and noone did anything about it.
I was so excited about the game, because I had many expectations but now...I am just expecting the worse, at least, nothing more then a number 2 after Top Spin 4. (Eventhough it is also not the perfect tennis game for me. For me the perfect tennis game is made out of real animations, sound-effects, playstyles and behaviour of the players, real sounds and atmosphere of the stadiums and on the court and at least the Top 15 players of each tour WTA/ATP and a real career mode with the original format of playing it. Some little things like injuries during a match, real stamina effects, raquet breaks, learning AI (reacting to your playstyle)
But it seems, like it is too hard to make such a game but I don't understand why. It should be a game with the sounds and presentation of Grand Slam Tennis 2, Dream Match Tennis and of the Top Spin Series.
I will buy Grand Slam Tennis 2 anyway...For me thats clear
But I guess, I will not be totally happy about the game afterwards. Or maybe, there will be a big surprise and everything will be different and better - who knows.
