Quoted from Mato:WOZ was number 1 for a week or 2 and dropped pretty fast, you will find Metallica will do the same......
i think WoZ was a unique case.
There's WAY more polarized feelings about the game,
And there's FAR fewer people that have even had a chance to play one (especially a production-grade model with current software).
I think WoZ will actually climb back up over time as more get into the wild and people can play it and make an INFORMED opinion (rather than respond to the drama on pinside).
