Yeah, the people heckling at the forums there seem to be pretty agreed that they want a MMORPG and nothing else. Which strikes me as odd, seeing as how MMORPGs tend to lend themselves to goldfarming and a lot of other unsavory habits.
Plus, a game has to be a proven franchise before a company will sink in the millions necessary to build the servers and do the programming and testing necessary for an MMO game.
See: D&D Online. After something in the realm of 40 years of abuse in the computer world, D&D finally got an MMO. An MMO that is fun and actually makes me want to play D&D more often (I'm currently down to once, maybe twice a month).
I'm not sure how a Shadowrun game would need to be structured to keep everyone happy, but it seems to me that in order to bring in the greatest number of fans, you'd need a popular gametype (such as an FPS) to appeal to people who knew (Or know) nothing about Shadowrun. I'm afraid that if they did make a Shadowrun MMO, it would turn out like Star Wars Galaxies, and suck so much ass that people who used to like star wars would stop playing it.
Anyway, I'm just stuck at school until my next class starts...
