Nothing against True20 or Modern20, as I think they're both awesome systems

But, with WotC, I'd like to see some specific stuff come out that would fit the d20 Modern mold (due mostly to copyrights): Star Frontiers (as a full game), GI Joe (which would be a great tie-in for 2k9), Gangbusters, Boot Hill, Gamma World and Top Secret. Single books for each with some web support would be great ... or even a few books.
As much as the TSR gamer in me want the above to happen, we have to be real, not overly nostalgic.
It needs a starting focus first, what with being a new game and franchise, not unlike the long-running
D&D or well-established fan-derived
Star Wars. They need to relaunch it with one setting in mind first. Later they can expand and add new settings, until the fanbase for
d20 Modern can grow as much as
D&D fanbase.
We need to reform the rules so that it is simple yet can emulate cinematic "movie" actions, from the grittiest of films, or over the top stunts (and somewhere in between). I hope that the rules do not derived from
D&D 4e, even though the accountant in me says it's best to cater to the much larger
D&D fanbase, which mean more customers can enjoy
d20 Modern 2.0 better than the existing one, which means more profit coming in. (Of course, one can argue that most
D&D fans only care for
D&D, period.) Using the
Star Wars rules is a good template for the new
Modern rules. The rules also have to be modular, meaning I can plug-in or plug-out any elements I choose for my own type of
Modern game. If I want to play with magic or without, I can do that. Plug-ins not only have to work seamlessly with the core rules but with other plug-ins. If I want to play magical mecha game, it should work with as little critical flaws as possible.
