(Besides, I know who Scrappy Doo is . . . I have seen the occasional Scooby Doo episode; I just never watched this stuff regularly as either a kid or an adult.)
People can say "I hope they're not planning to . . . " after reading JUST solicitations / interviews; people can make judgments on if they think they'll bother to buy it or not. But do you HAVE TO make all these threads about stuff you REALLY don't know a whole lot about yet (though you make it SOUND like you do)?
Can't it be that there's an evil Scrappy-Doo CLONE as well as a good Scrappy-Doo held prisoner or something?
