Here is what stands out to me
The PS3 launched in EU last and managed to have their first big sales surge finally in Week 18 due to the EU launch. Since then they became the dominant console of choice all over EU which stands today. So the Playstation basically owns the EU market.
The Wii didn't get much of a boost from either the EU or Japan launches.
The Wii U didn't get much of a boost from EU launch, but definitely got a boost from the Japan launch.
The X360 really only sells in the US.
Future prediction
Playstation will continue to own Europe market
Xbox will continue to own American market
Nintendo will dominate Japan market
