MGQ3 Demo Soon
According to Torotoro’s twitter (https://twitter.com/torotoro_mon/status/304014352569204736) the MGQ3 Demo will be out sometime on the 23rd Japan Time (Or any time after around 10am Friday). Depending on how long and how changed the system/interface stuff is from the previous parts, it could take a few hours (from when I first start) to a few days for it to be translated and out.
He also said that just because the trial is out it doesn’t mean the full game is right around the corner. There was about 3 months between part 2’s trial and release… But I don’t even know if that’s a good benchmark to go by.
