The thing about editorials is that they are usually reactionary...so the best ones only come out when there's something to talk about. And right now, there aren't a lot of surprises or big news items coming out worth writing a whole article about. If you read our mailbags (which also aren't frequent enough, but they're more common than editorials), you'll find mini-editorials on all kinds of smaller issues.
When GameCube was first announced up until the first year or so of its lifespan, there were tons of things to editorialize on, while other kinds of content (such as reviews) couldn't take up much of the limelight. Now it's the opposite; plenty of games to write about, not so many issues to rant on or investigate. That process will reverse itself again as the new systems begin to be unveiled next year. So just sit tight!
And in the meantime, I'll try to think extra hard about things to write about. ;-)
