Yeah, I know about those ones... I saw them in the book with three redecos of Starscream that were noted as "unreleased Gen2", but didn't see where it said "unreleased Gen1" next to the "coneheads". :o
Still, there were 31-ish unreleased Gen2 toys that were included in the book, plus a few others we've known about... which is a lot that they had in the pipeline when the line was axed.
(each time I go back to that book for something, I get so distracted at all the purdy pictures)
