current time for case processing in Islamabad

Hi,
I sponsored my family under family sponsorship for Canadian immigration in 2004. In January 2007 I heard from them and they asked for some documents (like my work letter etc).... and then the case was sent to Islamabad... in October my parents were asked to provide some documents, original etc..

I am wondering how long does it take to process such cases these days for Pakistan... from the profile above any experienced guess how long will it take (assuming everything goes fine) ... I am working full time here in Canada for a while now and my history is pretty good so I am not expecting any delay from my check which I think was completed this year when the file was sent to Islamabad...

So, any idea on the processing times these days... has anyone had similar case processed lately..?

thanks for your help
