I think Konami should keep PES5 as the main game, as the Core Gameplay..
But we should really be seeing something better from Next Gen Consoles.. we should be seeing player's finally coming to life; more Types of Movements, more Stats and Special Abilities, etc, etc..
PES should stick to their roots -but- they should work on the Animations. Asides from running Realistically, we should also Notice Significant Differences between each player's Movements.
This is Evidently Not the case with PES09 -but- this is what should be accomplished with PES 2010. Keep the same PES5 Gameplay, but with Great Animations.. that's where Next Gen Football Sims are failing the most.
Animations; different styles of "Trapping" the ball, touches with the Outside and Inside of the Foot, different types of Slow Dribbles, etc, etc.. Players that actually Look as thought they are "Dribbling" with the ball -instead- of just Running with the ball.
Just Imagine PES5 with great Graphics and great Animations.. it CAN be that good.
