yeah that does look like crap...
Tennis games are usually some of best looking games on any system... due to the fact that there isn't much to render... you have a cort and 2 players and the rest is fluff... the court can be done with as little as 2 figgin polygons meaning that all the detail can go into making the characters look as real as possible...
I attribute the crappyness to
-jaggies, in tennis games jaggies especially across the top of the net is annoying as hell
-lack of shaddows/read time lighting... seriously where are the player's shaddows?
-poor character modesl, the models are OK in spots and crap in others... the legs and faces look pretty good but the arms and clothing look horrid.
-incorrect resolution... if it's not 1280x720 it's not a true screenshot IMO.
At this point the current gen Top Spin honestly looks better than this
I agree.. why bother releasing pictures.
As for people getting disappointed with next gen screenshots... only us nerds who care about the 360 look at these things... my non-nerdy friends who inquire... I show them the PRG3 trailer and the WarDevil trailer... that's all they need to see
