What is the impact of the new google+ share button on SERP

[SherWeb]

Hello mozzers,

I'm currently wondering what will be the impact of the new social signal ( Google+ Share ) on SERP an organic traffic.

As we all know by now , Facebook share have an higher social signal authority then the Facebook like on SERP  @Randfish posted some great info at:

Since Google rolled out the new Google+ Share social signa at :

https://developers.google.com/+/plugins/share/?utm_source=blog&utm_medium=gplusdevelopers&utm_campaign=shareplugin

I was wondering if somebody had the chance to do some clear testing on the SERP impact of this new social signal even if its a fresh addition to the social signals.
