On the Pakwheels forums, there has been a lot of buzz that given the current situation of CNG, govt might want to move to LPG. Heretofore there has been no activity on the LPG front except from rumors, but a few weeks ago the SSGC LPG terminal at Port Qasim has been inaugrated, Engro is going along with their EVTL LPG terminal in the same area and now this ad in the newspaper surely tells that consumers are being prepared for the introduction of LPG.
The SSGC LPG Pvt. Ltd. website does not have any content right now, and you'll be greeted with this 'coming soon':

Point is, when CNG was launched, it was tauted to lessen our dependence on imports. If we have to import anything at all, why not diesel/petrol/HFO (basically crude oil), since the infrastructure is already in place?
[This post goes into the CNG forum since there is no dedicated LPG forum, or a neutral 'alternative fuels' section for that matter].
