Quick read of the seabass interview , next gen ? , next gen stadiums yes as old gen ones would not run on the 360. So they rewrote/rebuilt the stadiums in PES for the 360.
Did you rewrite the AI gameplay NO ! They have kept the PS2 AI gameplay and tweaked it for the nextgen 360. Might be a big tweak but still a tweak and not a 360 version of PES built from scratch for the next gen consoles ...
I hope I really do , that keeping the PS2s base AI gameplay and "tweaking" it for the 360 NG version, does not mean that all the old annoying niggles glitches call them what you will from the PS2 reappear in the next gen game , but I would not hold my breath on that one ...
My take on it , if they keep making PES for the PS2 and then taking that base game and tweaking it for the next gen , then you are not going to get a TRUE nextgen game, bulit from scratch using the power of these NG consoles, there AI power which would take football to the next level..
That will not happen as long as they keep PES tied to the PS2 , and use the base frame work of that game and tweak the graphics and AI ....
