As R9NALD9 has said, I really wouldn't buy the Konami story of having worked on this game for the past 2-3 years. It genuinely sounds like nonsense to me, especially after they claimed to have been working on PES2010 while actually being in the process of creating the previous PES2009. They probably thought of a front cover and considered that to be developing work on the next installment.
Honestly, after being a PES fan since 1998, I don't take anything Seabass says seriously anymore unfortunately. It's a shame really, but he and Konami are clutching at straws at the moment and they're caught in two minds. They need to satisfy their home region of Asia with fast, arcade-like football, while the western world wants a real experience and simulation. PES2011 may have introduced this old/new gameplay speed bar but that won't change the gameplay itself completely of course.
