Why the delay CRA? NETFILE software certification still on-going!?

The Canada Revenue Agency NETFILE service has been officially open to receive 2013 tax returns since this past Monday February 10th. Yet only a handful of packages have completed the certification process. Today, for the first time there is a list of packages "in process" to at least let people know which are likely to get certified. Still, it's quite shocking that things are so late, especially since CRA is promoting online instead of paper filing. I cannot imagine that all those software companies, including the biggies TurboTax and UFile, have been sitting on their hands. So what gives CRA? Will the April 30th tax submission deadline will be extended to compensate?
