"console war over" implies there ever was a war. Well, okay, there still is a war between MS and Sony. Nintendo wasn't fighting in any war, they just went off and took everything without a fight.
To use an RTS metaphor, MS and Sony are throwing wave after wave at each others' main bases, Nintendo moved its forces out of its own a long time ago and was declared dead for it but now they're grabbing all the expansions MS and Sony haven't taken (or even abandoned) while the other two have almost mined all the resources in their main and spent it on defenses or failed attacks. It's just a matter of time until they realize their situation and punch in "gg".
