The 9th Kobe Animation, Director Kenji Kamiyama attends and accepts an award for his work on 'Stand Alone Complex' and was interviewed by the MC - very briefly revealing to the crowd that they should expect (or rather 'imagine' a sequel, in relation to his upcoming work) a sequel to 2ng Gig.
As the bit of info has come to light in English now, some time after the event, who knows for certain what he is refering to exactly? Speculation? Maybe he meant the 'Laughing Man' movie (which contains new footage) or a new movie entirely, or perhaps it is a 3rd Gig? Anyhow, plenty of other stuff to enjoy until we know for certain.
