So really, they might just be the mailman, but it's still a mailman that will tell it's boss what's happening around. I do believe that people asking for SIV on it falls in the "Suggestions" and "developmental" categories.
Every little bit helps, and I've read the emails between KC_MCDOHL and various staff at Konami Japan and they've all been favourable, with people being happy that we care so much about the series.
And whatever happens, I'm happy by the fact that they aren't saying that the series is dead and are all hinting at some hope.
