I think it is very old news now, because when they successfully launched Geo News and Geo tv. when Geo network was dominant, in those days they announced to launch 8 more channels out of which 2 more came in 2005, famous Geo Super and AAG. When their 5th channel came which was Geo English in 2008 it didn't manage to got the required trp's and then Global financial crisis, all things sums up thus resulting in shutdown of their English channel project. After that Lackson group popular Express News became the 2nd most watched channel in early 2008 just after its launch of few months. Later more channels were launched two of them are prominent Dunya News, Samaa.
Thus, things were not the same for Geo tv network as was before. It lost its credibility and trust among viewers in the mid of 2009 because of some specific things and controversies. Then in early 2010, Express News came up as the most watched channel breaking the years of record of Geo News. There are many reasons that Geo tv's future projects were closed. As for now they have to attain the same position in the market rather than launching new channels.
If future channels are concern the only accurate information is about Lackson media's 3rd channel which is going to be a complete Entertainment channel. It was officially announced in their Express Festival.
