"As you can see, Konami’s soccer games received a nice large bump this year as compared to the last. This can be attributed to the release of Pro Evolution Soccer 2011 in Europe, as well as follow-ups to Pro Evolution Soccer 2010 in the form of Pro Evo Soccer 2010 – Arcade Championship for arcades and Pro Evo Soccer 2010 – Aoki Samurai no Chousen."
This is because PES launched in Q3 last year, while it did in Q2 this year. Explains a lot.
