I'd love to see a Goodman 4E DM screen. If you could incorporate something like the Paizo combat/initiative pad (the one with the magnets) for 4E, I would be so pleased that I'd throw sweaty wads of rolled up cash at Joseph Goodman.
Paizo has been very wishy-washy about whether or not they are going to support 4E, about how much they are going to support it. They've also been a little jerky about it. I've actually stopped buying from Paizo altogether.
I think right now would be the best time for Goodman Games to step up and compete with Paizo more that they already are on these types of things. If GG gets the ball rolling now for 4E they can gain a lot of business by providing to those of us who will be playing 4E right off the bat with all the gaming materials we need. A Pathfinder type adventure path/campaign setting would be cool too. I also think most people who are hesitant about it will eventually make the switch after it's been out for a short while, so I think as a business decision it would be a smart one to pump out these products as early as possible. I'm ready and waiting anyway...
