fuzzy: I also remember hearing about how the Duelist was supposed to go online, or at least parts of it on WOTC's website. For me, that meant yet another site to go to so I haven't bothered to see if they've actually done that.
But I agree with everyone's assessment that the Duelist was better. But I also think that it won't come back because I don't think the circumstances have changed for the better; the reasons why they got rid of the Duelist still hold, and worse yet, the rumored cutbacks of Magic staff don't help (I mean, a periodical is probably the first place they'd come from).
