Not a teaser, a trailer. Like the one we saw for Poison back at Comic-Con. That also means it’s more entertaining than the 20-second character teasers we’re accustomed to seeing. In this one, Rufus mistakes Bob for Ken Masters:
Ishaan specializes in game design/sales analysis. He's the former managing editor of Siliconera and wrote the book "The Legend of Zelda - A Complete Development History". He also used to moonlight as a professional manga editor. These days, his day job has nothing to do with games, but the two inform each other nonetheless.
