I would wait yes. I am seriously tempted to rip the site apart and start again, but I need to understand why Google thinks its low quality. The articles certainly aren't, but there must be something that is tripping it up.
At the moment I suspect it is a lack of domain authority. The sites that rank above me have better authority, albeit worse and duplicate content.
Therefore I think this algorithm only kicks in for lower auth sites, otherwise the very thin, but branded, price comparison sites would not be above me.
