Here is the quote:

"I'm not touching or even hinting at that in fear of Sega will make it official and make me look stupid. That said, I don't think Sega will ever delve into Silver's back-story. Short of cameo appearances or non-main-series games, I think we've seen the last of him. All that said, I'm sure he'll remain a familiar face. And given how much SegaSonic parallels Dragon Ball Z, I'd wager Silver is somehow descended from Shadow and Amy. Don't ask me how that'd work - I'm just going off the patterns."
